I use jj key chord to jump to a char quite often, but sometimes I do a certain action that disables it, I think it happens after using it in combination with a mistaken key. I can't seem to figure out when that happens though. I need to reopen my buffer to re-enable the jj jump to char key chord. Any ideas what's happening or how to figure it out?

@bbss it sounds like something is changing the mode that your jj is enabled for. The next time it happens, I would use C-h b to check if anything has chenged the bindings for jj. Next I would check the modes the current buffer has enabled and then do M-x revert-buffer (this should have same effect as reopening the file) If it works, I’d check the modes again and compare
