  • Ctrl-S: Halt output to screen. [ 18]

  • Ctrl-Q: Reactivate output to screen.

  • up-arrow: Start command history search.

  • Ctrl-R: Start incremental command history search.

  • TAB: Complete input of the filename to the command line.

  • Ctrl-V TAB: Input TAB without expansion to the command line.

Other important keystrokes to remember:

  • Left-click-and-drag mouse: Select and copy to the clipboard.

  • Click middle mouse button: Paste clipboard at the cursor.

Here, in order to use a mouse in the Linux character console, you need to have gpm running as daemon. [ 19] See Mouse configuration, Section 3.3.
