I still not fluent with Magit's terminology and workflow. Probably because I'm not using git in general too often. When I do, and when I try to use Magit as the interface, I usually get confused by the wealth of options and switches, and resort to the terminal.
Today I decided to give Magit yet another try. I read the this Getting Started guide, and now things makes much more sense. However, I can see how I forget what I've just read a week from now, so here's the gist of that, my simplest cheat-sheet:
(Ma)git status:
C-x g
(Ma)git add
For each unstage file:
s
(Ma)git commit
c c
Type the commit note and then C-c C-c to create the commit.
(Ma)git push
p u
Done. Now I can type q to close the Magit pop-up buffer, and be back on the file I was working on.
