Below I provide a very brief list of emacs commands covered in class.
( "^" denotes the control key; <esc> denotes the escape key)

^x^s                save the file
^x^c                exit
^d                  delete character at cursor
^e                  go to end of line
^a                  go to beginning of line
^k                  kill line to buffer
^y                  yank from buffer
<esc> <space bar>   mark start of block
^w                  kill block (from mark to cursor) to buffer
<esc> x compile <enter> <enter>
                    run the command make
^x `                (that little thing is a back quote) go to line with error
^z                  put emacs in background
fg                  (on command line) put emacs in foreground
<esc> >             go to bottom of file
<esc> <             go to top of file
^x i                insert file at cursor
^x ^f               load file into buffer
^x 1                close second window
