Somehow I managed to get QtCreator’s text mode into –COMMAND– or –INSERT– mode.
I don’t care what it is or how it works. How do I get rid of it?
All I care about is normal text-editing without these strange modes.
One of them lets me select text-parts but not delete them.
My mouse-cursor is now even missing.
May be, you’ve enabled
fakevimin settings. Then, disable it.
