| - | |||
| - | === Entering Scrollback Mode and Navigating === | ||
| - | |||
| - | |||
| - | To enter scrollback hit C-a [. A status line will indicate that you've entered copy mode. To exit scrollback mode, hit the escape button. | ||
| - | |||
| - | Navigating in scrollback mode will be pretty familiar to VI users. Here are some of the most common navigation keys (taken from the screen manpage): | ||
| - | |||
| - | <code text> | ||
| - | h - Move the cursor left by one character | ||
| - | j - Move the cursor down by one line | ||
| - | k - Move the cursor up by one line | ||
| - | l - Move the cursor right by one character | ||
| - | 0 - Move to the beginning of the current line | ||
| - | $ - Move to the end of the current line. | ||
| - | G - Moves to the specified line | ||
| - | (defaults to the end of the buffer). | ||
| - | C-u - Scrolls a half page up. | ||
| - | C-b - Scrolls a full page up. | ||
| - | C-d - Scrolls a half page down. | ||
| - | C-f - Scrolls the full page down. | ||
| - | </code> | ||
| - | |||
| - | I often use the page up and page down commands to quickly scroll back through the window's history. | ||
| - | |||
| - | In addition to traditional navigation, Screen allows you to search the scrollback buffer using the following commands: | ||
| - | |||
| - | <code text> | ||
| - | / - Search forward | ||
| - | ? - Search backward | ||
| - | </code> | ||
| - | |||
| - | Search is a very useful feature. For example, you could run a script and search for keywords in the output (such as Error), without having to redirect the output. | ||
