- <RETURN> Insert a newline <TAB> Advance to next tab stop
- ^J Insert a newline and indent M-^W Delete paragraph
- ^O Open (insert) line
- ^W Delete region between mark (set using M-<spacebar>) and cursor
- M-W Copy region to kill buffer
- ^X^O Delete blank lines around cursor
- -----------------------------------------------------------------------
- => (3) SEARCHING
-

- ^R Reverse search from cursor position.
- ^XS Forward incremental search
- ^XR Reverse incremental search
- <ALT> S Search for the next occurence of the last string (IBM-PC only)
- <ALT> R Search for the last occurence of the last string (IBM-PC only)
- -----------------------------------------------------------------------
- => (4) REPLACING
-
- M-R Replace all instances of first typed-in string with second
- typed-in string. End each string with ESC.
- M-^R Replace with query. Answer with:
- ^G cancel . exit to entry point

- -----------------------------------------------------------------------
- => (6) REGIONS & THE KILL BUFFER
-
- M-<spacebar> set MARK at current position
- ^X^X eXchange mark and cursor
-
- A REGION will then be continuously-defined as the area between the mark and
- the current cursor position. The KILL BUFFER is the text which has been
- most recently saved or deleted.
- -----------------------------------------------------------------------
- => (7) COPYING AND MOVING
-
- ^W Delete (Wipe) region M-W copy region to KILL buffer
- ^Y Yankback save buffer at cursor
- Generally, the procedure for copying or moving text is:
- 1) Mark a REGION using M-<spacebar> at beginning and cursor at end.
- 2) Delete it (with ^W) or copy it (with M-W) into the KILL buffer.
- 3) Move the cursor to the desired location and yank it back (with ^Y).
- -----------------------------------------------------------------------
- => (8) MODES OF OPERATION
- ^XM Add mode in buffer M-M Add global mode
- ^X^M Delete mode in buffer M-^M Delete global mode
- OVER Replaces (overwrites) rather than inserts characters
- WRAP Turns on word wrap (automatic newlines)
- VIEW Allows viewing file without insertion and deletion
- CMODE Automatic indenting for C program entry
- EXACT/MAGIC Changes how search and replace commands work (see next page)
- -----------------------------------------------------------------------
- => (9) SEARCH AND REPLACE MODES
-
- EXACT Uppper/lower case is not ignored in searches
- MAGIC Regular pattern matching characters are active
- . Matches any one character

- file size and character under cursor
- M-^C Count words/lines/chars in marked region
- -----------------------------------------------------------------------
