One of the worst things about learning Emacs is to memorize and get that muscle memory regarding the chords required to do simple things like move half a page, yank this text, etc.
One of the ways that a lot of people get over this is by either downloading a cheatsheet poster or creating their own. This is nice and all, but you always have to leave Emacs in order to consult something, breaking your flow and making you less likely to check it.
We plan on fixing that by writing a tiny package where you define the commands you want executed, we grab the chrod associated with that from the help, and even allow you to set a small description about that chord. Then whenever you want to consult your own personalized cheatsheet we open a minibuf, or a small bottom buffer like help does, and display a nice tabular view with your cheatsheet.
