All of these can be changed in Settings ▸ Shortcuts (Ctrl ,). Changes apply immediately.

Rebinding
In Settings ▸ Shortcuts, click a binding and press the keys you want.
- If the combination is already used by another action, Compose tells you which one rather than
silently taking it over.
- Any action can be left unbound.
- Reset all shortcuts restores every default at once.
Ctrl Y for redo and F5 for preview are fixed aliases. They work in addition to whatever the
rebindable shortcut is set to, and cannot be changed.
Editing text
Inside text fields, the usual editing keys work as they do everywhere — including Ctrl C,
Ctrl V and Ctrl X. Del deletes a character rather than the block when the cursor is in a
text field.
