Android Studio Electric Eel | 2022.1.1 Patch 1 - the latest one.
Everything was OK and either I hit a wrong short key combination and turned that on or it is a bug.
I have no idea what is that and definitely it's not useful for me, rather makes coding impossible when I need to select something since it just places the cursor everywhere.
What is this and how disable it?
You have enabled Column Selection Mode
. You can disable it under Edit -> Column Selection Mode
