+# Emacs Tips
+
+*Posted 2007-05-22, updated 2021-07-01.*
+
+These are some emacs keybindings (and other functions) that I once found useful. I've mostly used Sublime Text for the last few years, however.
+
+## Editing
+
+`C-[SPC]`: set mark
+`C-x C-x`: exchange point and mark
+`C-w`: kill (AKA "cut")
+`M-w`: kill-ring-save (AKA "copy")
+`C-y`: yank (AKA "paste")
+`M-h`: Put region around current paragraph (mark-paragraph).
+`C-x h`: Put region around the entire buffer (mark-whole-buffer).
+`C-u C-[SPC]`: Move in mark ring
+`M-d`: Kill word
+`M-[DEL]`: Kill word backwards
+`C-M-k`: Kill the following balanced expression (kill-sexp)
+
+## Registers
+
+`C-x r r`: Save position of point in register r (point-to-register).
+`C-x r j r`: Jump to the position saved in register r (jump-to-register).
+`C-x r s r`: Copy region into register r (copy-to-register).
+`C-x r i r`: Insert text from register r (insert-register).
+
+## Bookmarks
+
+`C-x r m [RET]`: Set the bookmark for the visited file, at point.
+`C-x r m bookmark [RET]`: Set the bookmark named bookmark at point (bookmark-set).
+`C-x r b bookmark [RET]`: Jump to the bookmark named bookmark (bookmark-jump).
+`C-x r l`: List all bookmarks (list-bookmarks).
+`M-x bookmark-save`: Save all the current bookmark values in the default bookmark file.
+
+## Miscellaneous
+
+``M-` `` shows the menu.
+`M-x highlight-changes-mode` toggles showing the changes you've made to the file since the last save.
