5 Notes

5.1 multiple-cursors

Some commands executed during multiple-cursors enabled may lead Emacs to go frenzy. Commands like window manipulation will be executed multiple times if mc is active. Not all Emacs commands may be compatible with mc.

To run interactive M-x commands with mc, run the command first. This will result with application of the command to the leading cursor. Then press C-: to apply the command to consequtive cursors. If this is not the case or you want a command to be executed only once, configure the mc/cmds-to-run-once variable of the layer like in the following example.

(setq-default dotspacemacs-configuration-layers '(
  (multiple-cursors :variables
                    multiple-cursors-backend 'mc
                    mc/cmds-to-run-once '(upcase-region))))
