https://sharpkeys.en.softonic.com/ looks so scammy, and I have ublock turned on... I can only imagine how it must look without that. I'm sure it's fine but why do all windows tool s always get hosted on the most scam looking websites?
When I'm stuck on windows I use https://docs.microsoft.com/en-us/sysinternals/downloads/ctrl...
Of course adding setxkbmap -option ctrl:nocaps to ~/.xinitrc seems way easier to me. But I'm probably in the minority.
