Move point to buffer and position of the last entry in the global ring (pop-global-mark). |
| Key |
Command |
| C-M-a |
Move to beginning of current or preceding defun (beginning-of-defun) |
| C-M-e |
Move to end of current or following defun (end-of-defun) |
| C-M-h |
Put region around whole current or following defun (mark-defun) |
| Key |
Command |
| C-M-f |
Move forward over a balanced expression (forward-sexp) |
| C-M-b |
Move backward over a balanced expression (backward-sexp) |
| C-M-k |
Kill balanced expression forward (kill-sexp) |
| C-M-t |
Transpose expressions (transpose-sexps) |
| C-M-n |
Move forward over a parenthetical group (forward-list) |
| C-M-p |
Move backward over a parenthetical group (backward-list) |

| Key |
Command |
| C-x r SPC R |
Record the position of point and the current buffer in register R (point-to-register) |
| C-x r j R |
Jump to the position and buffer 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) |
| C-x r + |
Append text to or increment register (increment-register) |
| Key |
Command |
| C-x a g |
Define an abbrev, using one or more words before point as its expansion (add-global-abbrev) |
| C-x a l |
Similar, but define an abbrev specific to the current major mode (add-mode-abbrev) |
| C-x a i g |
Define a word in the buffer as an abbrev (inverse-add-global-abbrev) |
| C-x a i l |
Define a word in the buffer as a mode-specific abbrev (inverse-add-mode-abbrev) |
