Enter copy/scrollback mode. This allows you to copy text from the current window and its history into the paste buffer. In this mode a
vi-like 'full screen editor' is active:
- move the cursor line by line or column by column.
- move to the leftmost column, to the first or last non-whitespace character on the line, respectively.
- move the cursor to the leftmost column of the top, center or bottom line of the window, respectively.
- positions one line up and down.
- moves to the specified absolute line (default: end of buffer).
- moves to the specified absolute column.
- move the cursor word by word.
- move the cursor WORD by WORD (as in
- scroll the display up/down by the specified amount of lines while preserving the cursor position. (Default: half screen-full).
- scroll the display up/down a full screen.
- moves to the beginning of the buffer.
- jumps to the specified percentage of the buffer.
emacs style movement keys can be customized by a .screenrc command. (E.g.
markkeys “h=^B:l=^F:$=^E”) There is no simple method for a full
emacs-style keymap, as this involves multi-character codes.
The copy range is specified by setting two marks. The text between these
marks will be highlighted. Press space to set the first or second mark
- used to mark one whole line or to mark from start of line.
- marks exactly one word.
Any of these commands can be prefixed with a repeat count number by pressing digits 0..9 which is taken as a repeat count.
C-a C-[ H 10 j 5 Y” will copy lines 11 to 15 into the paste buffer.
- Vi-like search forward.
- Vi-like search backward.
- Emacs style incremental search forward.
- Emacs style reverse i-search.
There are however some keys that act differently than in
vi does not allow one to yank rectangular blocks of text, but screen does. Press
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.
- joins lines. It toggles between 4 modes: lines separated by a newline character (012), lines glued seamless, lines separated by a single whitespace and comma separated lines. Note that you can prepend the newline character with a carriage return character, by issuing a ”
- is for all the
vi users with ”
:set numbers” - it toggles the left margin between column 9 and 1.
- press before the final space key to toggle in append mode. Thus the contents of the paste buffer will not be overwritten, but is appended to.
- toggles in 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.
This example demonstrates how to dump the whole scrollback buffer to that file: ”
C-A [ g SPACE G $ >”.
- gives information about the current line and column.
- exchanges the first mark and the current cursor position. You can use this to adjust an already placed mark.
- does nothing. Does not even exit copy mode.
All keys not described here exit copy mode.
