Rebinding your caps-lock key to control is a popular thing to do (though there are arguments against it, even if a bit pedantic). However, the language I find a lot of my time in uses runs of capitals pretty extensively.

Is there a caps-lock-mode that can simulate the behavior? (Without affecting existing keybindings of course, e.g. striking C-x C-s will not send C-X C-S.)

    You can always use M-u (upcase-word) and C-x C-u (upcase-region). With a negative prefix arg you could upcase some number of words that you just typed, e.g. M-- M-4 M-u to upcase the last four words.

  • @glucas That's what I've been doing (upcase-region), but it's not quite the same. Mar 27, 2015 at 20:15
  • Yeah - does seem like having an upcase minor mode you could toggle would be more convenient in such cases.
