A real PC keyboard for Android.
Ctrl, Esc, Tab, arrows and F-keys that Termux, vim and SSH actually understand. The maintained successor Hacker's Keyboard users have been asking for.
Open source · Apache-2.0 · No internet permission
CtrlC
Real keys, not text
Ctrl+C interrupts, Esc leaves insert mode, arrows walk your shell history. Termux, vim and SSH clients get the key events they expect.
~|\
The whole layout
Esc, Tab, Ctrl, Alt, Home, End, Del, arrows, and every symbol where your fingers expect it — including ~ and |.
android.permission.INTERNETNothing leaves your phone
No internet permission. The keyboard cannot send what you type anywhere, and the source is open (Apache-2.0) so you can check.
$0, foreverFree where it counts
Everything Hacker's Keyboard did stays free, forever. Optional extras later pay for the work.
