Regions
Regions are areas of text that you select to operate on. Operations can
including killing / deleting, copying, re-indenting, counting lines,
etc. Normally, you select a region by placing a 'mark' at one end-point of the
region you want, and moving the point (or cursor) to the other end before
invoking the command you want.
C-SPC set-mark-command. Places a mark at the current point or cursor
position.
C-x C-x exchange-point-and-mark. Move between the current position and the
mark.
C-x h mark-whole-buffer. Mark the entire buffer.
C-M-SPC mark-sexp. Mark the expression following the point.
Copying, Deleting, Killing and Yanking
Deletion means to remove text from the buffer without saving it. Killing
means to save the removed text, so that it can be yanked back later someplace
else.
C-d delete-char. Deletes the character to the right of (under, if
the cursor is a block that covers a character) the cursor.
-DEL delete-backward-char. Deletes the character to the left of the
+DEL or C-? delete-backward-char. Deletes the character to the left of the
cursor.
C-y yank. Yanks text, inserting whatever text you killed last.
C-w kill-region. Kills the region of text between the point and the
cursor.
M-w kill-ring-save. Save the region as if killed, but don't kill
it. AKA Copy.
C-M-w append-next-kill. If the next command kills text, append it to
the last thing killed instead of replaceing it.
M-d kill-word. Kills to the end of the word to the right of the
cursor (forward).
M-DEL backward-kill-word. Kills to the beginning of the word to the
left of the cursor (backward).
C-k kill-line. Kills to the end of the current line.
C-u 0 C-k kill-line. Kills to the beginning of the current line.
C-u -1 C-k kill-line. Kills to the beginning of the current line, and
previous newline character.
M-k kill-sentence. Kills to the end of the current sentence.
C-u -1 M-k kill-sentence. Kills to the beginning of the current sentence.
C-M-k kill-sexp. Kills the sexp after the cursor.
C-u -1 C-M-k kill-sexp. Kills the sexp before the cursor.
