File/Buffer/Window

-------------------

key combo resulting editor command

C-x C-f open a file

C-x C-s save buffer

C-x s save file (save-as)

C-x C-c quit

C-x 0 close current window (after splitting)

C-x 1 close any other windows

C-x 2 split window horizontally

C-x 3 split window vertically

C-x o move cursor to other window

C-x k RET close current file (“kill buffer”)

C-x b RET make window show other buffer

Select/Cut/Copy/Paste

----------------------

C-Space begin text selection

C-x Space begin vertical rectangle selection

M-h select current paragraph

C-g cancel

C-w cut

M-w copy

C-y paste

M-y paste next

Selections/Rectangles

----------------------

C-x r k Kill region-rectangle text, save last killed rectangle (kill-rectangle)

C-x r M-w Save region-rectangle text as last killed rectangle (copy-rectangle-as-kill)

C-x r d Delete the text of the region-rectangle (delete-rectangle)

C-x r y Yank last killed rectangle with upper left corner at point (yank-rectangle)

C-x r o Insert blank space to fill the space of the region-rectangle (open-rectangle)

This pushes the previous contents of the region-rectangle to the right

C-x r N Insert line no. along left edge of region-rectangle (rectangle-number-lines)

This pushes the previous contents of the region-rectangle to the right

C-x r c Clear the region-rectangle by replacing content with spaces (clear-rectangle)

C-x SPC Toggle Rectangle Mark mode (rectangle-mark-mode)

When this mode is active, the region-rectangle is highlighted and

can be shrunk/grown, and the standard kill and yank commands operate on it.
