[BUG] Cannot close tab using Ctrl+W as shortcut

I've set the shortcut for Close Tab to Ctrl + W and changed the SQL > Clear shortcut to Alt + BkSp but the Close Tab does not work on subsequently opened Query tabs. Could it be because it's one of the default shortcuts or is something else wrong?

In addition, it would be great if changing a shortcut would let you know if it's already used by some other command.

Cheers, Armin

Can confirm that.

Ctrl+W is concurrently assigned by default, in SQL > Clear and in Data > Clear. Even if I change both actions to Alt+BkSp, then Ctrl+W does not close any tab. Additionally, Alt+BkSp is also assigned a second time, in SQL editing > Undo. Note that there also multiple "Undo" actions there, with different shortcuts.

Totally broken.

Closing a tab works if I don't use the Ctrl key, but the Alt key instead for the shortcut, e.g. Alt+W.
