How to Change the Edge-Drop Toggle Hotkey

The default Edge-Drop toggle hotkey is Alt+C. It is a sensible default — Alt chords are less crowded than Ctrl chords, and C is mnemonic for clipboard — but it is not always free. Terminal multiplexers, IDEs, games, and IMEs all bind Alt+C to other commands. This article covers how to remap the toggle hotkey through the in-app recorder, which chords Windows reserves for the OS, which chords tend to conflict with popular apps, and how to recover from a stuck binding. For the sibling decision — whether to switch to hotkey-only mode after remapping — see how to turn hover off and use only the hotkey. For the onboarding context, see the first ten minutes with Edge-Drop.

Why remap

The hotkey is the keyboard path to the shelf. It is the trigger of choice when hover is off, and the trigger of fallback when hover is on. A hotkey that conflicts with another app is not just an inconvenience — the conflict is usually resolved by whichever app registered the chord last, which means the loser silently stops receiving the chord. The user presses Alt+C, nothing happens, and the shelf does not open. The first reaction is "Edge-Drop is broken"; the actual cause is that another app won the registration race.

Common conflict sources:

• Terminal multiplexers. tmux and screen use Alt chords heavily. WSL users running tmux inside Windows Terminal will see Alt+C consumed by tmux before it reaches Edge-Drop.
• IDEs. VS Code and JetBrains IDEs bind Alt+C to various commands (e.g., column selection mode in some configurations).
• Games. Many games bind Alt+C to a command (often camera or crouch). Edge-Drop's fullscreen suppression prevents the shelf from opening during the game anyway, but the chord is still consumed.
• IMEs. Some non-Latin IMEs use Alt chords to switch input modes.
• Other clipboard tools. Win+V uses Win+V (not Alt+C), but other third-party clipboard managers may bind Alt+C or similar chords.

If any of these applies, remap the hotkey to a chord that is free on the user's machine.

Where the setting lives

The Hotkey control is in the Behaviour tab of the Edge-Drop settings panel. To open the panel:

1. Click the Edge-Drop tray icon and choose Settings.
2. Or open the shelf with the current hotkey (default Alt+C) and click the gear icon.
3. Or right-click the shelf and choose Settings.

In the panel, switch to the Behaviour tab. The Hotkey control shows the currently bound chord. Next to it is a Record button (or similar, depending on version) that captures the next chord pressed.

The steps to remap

1. Open the settings panel and go to the Behaviour tab.
2. Click the Record button next to the Hotkey field. The field enters a "listening" state.
3. Press the desired chord. The chord is captured and displayed in the field.
4. If the chord is reserved or invalid (see below), the field shows an error and remains in listening state.
5. Click Save (or click away, depending on version) to commit.
6. Test by pressing the new chord — the shelf should toggle.
7. Test that the old chord no longer toggles the shelf.

The setting takes effect immediately. The choice is written to config.json under %APPDATA%\Edge-Drop\. For the on-disk layout, see where Edge-Drop stores data on disk.

Chords Windows reserves

Some chords are reserved by the OS and cannot be reliably registered by a user-level app. Edge-Drop's recorder will reject these:

• Win+L — locked. Reserved by Windows for lock screen.
• Win+D — show desktop. Reserved by the shell.
• Win+E — open Explorer. Reserved by the shell.
• Win+I — open Settings. Reserved by the shell.
• Win+V — open clipboard history. Reserved by the OS clipboard history feature.
• Ctrl+Alt+Del — secure attention sequence. Reserved by the OS at the kernel level.
• Alt+Tab — task switcher. Reserved by the shell.

If the user attempts to record one of these, the recorder will either reject it silently or display an error. The previous chord remains bound.

For the official list of Windows shortcuts, see the Microsoft Support page on keyboard shortcuts in Windows.

Chords that conflict with popular apps

Even if a chord is not OS-reserved, it may be claimed by another app. The recorder cannot detect this reliably — global hotkey registration is best-effort, and another app may have already claimed the chord. The conflict surfaces only when the user presses the chord and the wrong app responds.

Common conflicts:

The Alt+Shift+<letter> family is a useful default when Alt+<letter> is taken. Alt+Shift chords are rarely bound by other apps, and the modifier combination is ergonomic on most keyboards.

Choosing a new chord

A few principles for picking a new chord:

• Prefer Alt over Ctrl. Ctrl chords are crowded by editor shortcuts. Alt chords are less contested.
• Prefer Alt+Shift over Alt+Ctrl. Alt+Ctrl can be confused with Ctrl+Alt, which some apps treat as AltGr on European keyboards.
• Avoid Win chords. Win chords are mostly reserved by the OS (see above), and the ones that are not reserved are claimed by PowerToys, Stream Deck, and similar tools.
• Pick a chord that is reachable with one hand. A two-hand chord (Ctrl+Shift+P, Win+Alt+R) is slower than a one-hand chord (Alt+C, Alt+Shift+C).
• Pick a mnemonic if possible. C for clipboard, V for paste, S for shelf. The mnemonic is less important than ergonomics, but it helps with recall during the first week.

Pause-while-recording

While the recorder is in listening state, Edge-Drop pauses its other keyboard hooks to avoid double-capture. This means:

• The shelf does not open on the current hotkey while the recorder is listening.
• The recorder captures only the next chord pressed. If the user presses a sequence of keys, only the first complete chord is captured.
• The recorder times out after a few seconds if no chord is pressed. The previous chord remains bound.

If the user wants to abort the recording without committing, click the Record button again or click away from the Hotkey field. The previous chord remains bound.

Recovering from a stuck binding

A few failure modes:

• The hotkey does not toggle the shelf after remap. Another app won the registration race. Try a different chord.
• The old hotkey still toggles the shelf after remap. A second Edge-Drop instance is running with the old chord (e.g., both a Store build and a GitHub build). Quit one. See how to uninstall Edge-Drop cleanly.
• The Hotkey field shows a chord the user did not record. The recorder may have captured a stray keypress during recording (e.g., the user pressed Record, then accidentally hit a key while reaching for the intended chord). Re-record.
• The settings panel does not open. Open the shelf via the tray icon (right-click → Settings) instead of via the hotkey, to bypass the hotkey registration entirely. This is useful when the hotkey is bound to a chord the user has forgotten.
• The config.json file is corrupted. Delete config.json and restart Edge-Drop; a fresh default config is created with Alt+C as the hotkey. See Edge-Drop settings map: Behaviour, Position, Appearance for the broader settings recovery path.

Pairing the remap with hover-off mode

If the user is remapping because Alt+C conflicts, they are likely also moving toward hotkey-only mode. The combined workflow:

1. Behaviour tab → Hotkey → record the new chord.
2. Behaviour tab → Hover open → Off.
3. Test the new chord opens and closes the shelf.
4. Test the new chord does not trigger any other app.

With hover off and a non-conflicting chord, the shelf is reliably available on demand. For the full hotkey-only mode treatment, see how to turn hover off and use only the hotkey.

What the hotkey does not control

The toggle hotkey is one chord. It does not control:

• The clipboard capture chord. Edge-Drop captures on the standard Ctrl+C; there is no separate capture hotkey.
• The paste chord. Click-to-paste and Ctrl+V use the standard OS chords; the toggle hotkey only opens and closes the shelf.
• Pin/unpin shortcuts. Pin and unpin are context-menu actions in the shelf, not hotkeys. See how to pin and unpin items in Edge-Drop.
• Search shortcut. Search is a click action in the shelf, not a hotkey. See how to search clipboard history in Edge-Drop.
• Filter shortcuts. Filters are click actions. See how to filter text, links, images, and files.

When NOT to remap

Remapping is the right move when the default conflicts. It is the wrong move when:

• The default works. Alt+C is a sensible default; if it is free on the user's machine, there is no benefit to remapping.
• The user cannot find a free chord. On a heavily-customised machine, every ergonomic chord may be taken. The right answer is to free up a chord by remapping another app, not to pick an ergonomic disaster for Edge-Drop.
• The user is not the only user of the machine. A shared machine should keep the default chord so that other users know what to press.

Summary

Remap the toggle hotkey in the Behaviour tab via the in-app recorder. Avoid OS-reserved chords (notably Win+V, Win+L, Ctrl+Alt+Del), avoid common conflict chords (Alt+C if another app claims it), and prefer the Alt+Shift+<letter> family when Alt+<letter> is taken. Test after remap by pressing the new chord and confirming the shelf toggles, and by pressing the old chord and confirming it no longer toggles. If the hotkey does not work, suspect a registration race with another app or a second Edge-Drop instance running with the old chord. The remap does not change capture, paste, pin, search, or filter behaviour — it only changes the chord that opens and closes the shelf.
