    (2) DELETING & INSERTING

    M-D Delete next word
    ^K Close (delete) to end of line -----------------------------------------------------------------------
    (2a) MORE DELETING & INSERTING

    <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

    ^S Search forward from cursor position.
    ^R Reverse search from cursor position.
    ^X S Forward incremental search
    ^X R 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
    ! replace the rest Y replace & continue
    ? Get a list of options N no replacement & continue -----------------------------------------------------------------------
    (5) CAPITALIZING & TRANSPOSING

    M-U UPPERCASE word
    M-C Capitalize word ^T Transpose characters

    (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
    ^X M 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 carraige return).
    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

    file size and character under cursor
    M-^C Count words/lines/chars in marked region -----------------------------------------------------------------------
    (11) MULTIPLE WINDOWS

    ^X 0 delete current window ^X P Change to previous window
    ^X 1 delete all other windows M-^V Page down next window
    M-^Z Page up other window -----------------------------------------------------------------------
