There are, however, some keys that act differently here from in
Vi does not allow to yank rectangular blocks of text,
screen does. Press:
c or C to set the left or right margin respectively. If no
repeat count is given, both default to the current cursor position.
Example: Try this on a rather full text screen:
C-a [ M 20 l SPACE c 10 l 5 j C SPACE.
This moves one to the middle line of the screen, moves in 20 columns left, marks the beginning of the paste buffer, sets the left column, moves 5 columns down, sets the right column, and then marks the end of the paste buffer. Now try:
C-a [ M 20 l SPACE 10 l 5 j SPACE
and notice the difference in the amount of text copied.
J joins lines. It toggles between 4 modes: lines separated by a
newline character (012), lines glued seamless, lines separated by a single
space or comma separated lines. Note that you can prepend the newline
character with a carriage return character, by issuing a
v or V is for all the
vi users who use
:set numbers - it
toggles the left margin between column 9 and 1.
a before the final space key turns on append mode. Thus the contents of the paste buffer will not be overwritten, but appended to.
A turns on append mode and sets a (second) mark.
> sets the (second) mark and writes the contents of the paste buffer
to the screen-exchange file (/tmp/screen-exchange per default)
once copy-mode is finished. See Screen Exchange.
This example demonstrates how to dump the whole scrollback buffer to that file:
C-a [ g SPACE G $ >.
C-g gives information about the current line and column.
x or o (’oh’) exchanges the first mark and the current cursor position. You can use this to adjust an already placed mark.
C-l (’el’) will redraw the screen.
@ does nothing. Absolutely nothing. Does not even exit copy mode.
All keys not described here exit copy mode.
