3. The Termux Keyboard and Special Keys
Command-line interfaces rely heavily on keys like Ctrl, Alt, and arrow keys, which are often missing or hard to access on standard mobile keyboards. Termux provides a unique solution.
The Extra Keys Row
Termux includes a specialized row above the standard software keyboard (if you are not using an external keyboard). This row contains essential modifiers.
| Key | Description | Usage Example |
|---|---|---|
| Ctrl | Control Key | Ctrl + C (Stop process) |
| Alt | Alternate Key | Not commonly used, but available |
| Esc | Escape Key | Exit menus or Vim |
| Tab | Auto-completion | Hit Tab to complete commands/filenames |
The CTRL Modifier
The most important shortcut is accessing the Ctrl key. Simply tap the CTRL button in the extra keys row, and then tap the desired letter.
| Shortcut | Function |
|---|---|
Ctrl + C | Interrupt or stop the running process. |
Ctrl + D | Send EOF (End of File); logs you out of a session. |
Ctrl + Z | Suspend the current process (send it to background). |
Ctrl + L | Clear the screen (same as typing clear). |
Accessing Function Keys (F1-F12)
Termux uses combinations involving the Volume Down button to simulate function keys and other crucial inputs.
- Volume Down + Q: Simulates the Tab key (useful if the extra keys row is hidden).
- Volume Down + L: Simulates the Ctrl key.
- Volume Down + 1-9 or 0: Simulates F1 through F10.
- Volume Down + P: Simulates the Up Arrow key.
