My shortcut for launching the #gitAnnex #magit transient buffer in #emacs is SPC g a. Sensible stuff; Space(prefix) Git Annex.
Now consider that #magit-annex's transient command shortcut to execute the sync function is y and then y again to sync all remotes.
I've been typing that combination dozens of times a day for a long time before I noticed :D
(Not that I have any plan to change it ;) )
