It would be really helpful to use a keyboard shortcut to comment out selected lines when working in the SQL Commander. I couldn't find anything in the docs about this feature already existing. Something like Cmd+/
On macOS with the macOS key map in Tools->Tool Properties and under the General / Key Bindings category the default bindings are:
Comment Selected Line: shift+command+R
Comment Selected Block: shift+command+B
These are listed in the Edit main menu.
Ah, brilliant. Thank you so much!!
