Default shortcut keys for custom commands are ctrl+1, ctrl+2 and ctrl+3 This only works on QWERTY keyboards. My AZERTY (French) keyboard have those keys as:
Keyboard | | | | -|-|-|-| QWERTY | 1 | 2 | 3 | AZERTY (shift) | 1 | 2 | 3 | AZERTY (no modifier) | & | é | " |
Even if I press Ctrl+Shift+&, it does not trigger the first custom command (sort, in my case, see #2582).
So I had to change the key binding in the settings (hopefully, it's great that this is possible!):
Key binding | Before | After | -|-|-| Send to custom command 1 | `<Primary>1` | `<Primary>ampersand` | Send to custom command 2 | `<Primary>2` | `<Primary>eacute` | Send to custom command 3 | `<Primary>3` | `<Primary>quotedbl` |
Would it be possible to set those by default if French keyboard is used? Maybe not.
