There seems no shortcut for directly switching to tabN.
If i want to switch tab from the 1st one to the 5th, i have to tap Alt+] for 5 times, which is not handy, Alt+5 is more convinient.

Currently, Alt+num is used to open different menu item.
I think shortcuts for such operations should be changed to other ones, eg alt+V for "View" and alt+M for "Mode", and make Alt+num available for tab switching (just like what xshell/terminus do)
