Customising Hotkeys

Rebinding the keyboard shortcuts used on tuning pages

The Hotkeys page lets you change the key bindings for every action exposed as a hotkey — table editing, navigation, save / reload, undo / redo, and the row-0 variants used on the Boost page. The default shortcuts are listed in Keyboard Shortcuts; this page is only needed if you want to rebind them.

Opening the Hotkeys page

From the top menu bar, click Options → Hotkeys. The Hotkeys page appears as a two-column table:

Hotkey — the current key sequence for this action.
Function — the action that the hotkey triggers (read-only).

Rebinding a hotkey

Double-click the Hotkey cell for the row you want to change.
Press the new key combination (including any modifiers such as Ctrl, Shift, or Alt).
Click anywhere outside the cell, or press Enter, to commit the change.

The new shortcut takes effect immediately — there is no need to restart. To clear a binding, double-click the cell and press Backspace until the field is empty.

Restoring defaults

At the bottom of the Hotkeys page, click Reset to Defaults to restore every binding to the values shown above.

Where hotkeys are stored

Customised bindings are persisted to %LOCALAPPDATA%\DigiTune\GTS\hotkeys.json. The file is created automatically the first time you change a hotkey; until then, defaults are used. Deleting the file resets every binding.

Note — Conflicts DigiTune GTS does not currently warn you if two actions share the same key sequence. If a shortcut stops doing what you expect, check that you haven't unintentionally bound the same key to two actions.
