On: IRC and Emacs all the things

Not using emacs, I could answer, but I have no idea what "M-f/M-b or C-a/C-e" means

M-f/M-b = Meta-f/Meta-b (the Meta key is usually mapped to the Alt key on typical PC keyboards): move forward/backward a word. In vim, the equivalent is normal mode w/b.

C-a/C-e = Control-a/Control-e: move to beginning/end of line. In vim, normal mode 0/$.
