I’m totally dependant on Sublime, but something horrible suddenly happened.
I cannot click inside an open file with the mouse to position the caret, select text, etc. The caret can only be moved with keyboard.
Have I pressed some magic key combination that disables mouse selection?
Please help 
I tried upgrading to ST3 build 3035, but same problem.
I had the same problem a couple of times in the past. The cursor is no longer visible, but you can still move it around and type. No mouse interaction.
I think I have similar bug repeating for already a year. Today I was finally able to reproduce it. Combination of keys is ctrl + (x and c at the same time).
Does this forum serve as issue tracker or should I try to report bug somewhere else?
