I using Ubuntu on VirtualBox (Host Windows10 Home 1903.)
I have replace CapsLock to Ctrl only on Ubuntu. (not replace key on Windows10 Host).
When I use vim I use Ctrl-[ (actually Caps-[ ) to back to normal mode, but it get stuck Ctrl so I need push Shift-Caps to purge stuck of ctrl for each time (actually Shift-Caps).
I would like to replace Caps to Ctrl on Ubuntu VM only (not Windows Host).
How do I avoid stuck Ctrl on ubuntu?
Note that I do not enable sticky key function.
