The keyboard at a glance

QNX SDP8.0User's GuideUser

The table below describes how the character-device drivers interpret various keys and keychords (groups of keys that you press simultaneously). The drivers handle these keys as soon as you type them.

Note:
Your keyboard might not behave as indicated if:
  • The driver is in raw input mode instead of edited input mode.
  • You're working with an application that has complex requirements for user interaction (e.g., the application might take control over how the keyboard works).

    or:

  • You're working at a terminal that has keyboard limitations.
If you want to: Press:
Move the cursor to the left (left arrow)
Move the cursor to the right (right arrow)
Move the cursor to the start of a line Home
Move the cursor to the end of a line End
Delete the character left of the cursor Backspace
Delete the character at the cursor Del
Delete all characters on a line CtrlU
Toggle between insert and typeover modes (if an application supports them) Ins
Submit a line of input or start a new line Enter
Recall a command (see below) or (up or down arrow)
Suspend the displaying of output CtrlS
Resume the displaying of output CtrlQ
Attempt to kill a process CtrlC or CtrlBreak
Indicate end of input (EOF) CtrlD
Clear the terminal CtrlL

When you use the up or down arrow, the character-device driver passes a back or forward command to the shell, which recalls the actual command.
