### Input
The `key_codes` example can be a useful tool to see how the library reacts to various key presses.
* **Basic set**: All simple key press (without shift, alt or ctrl pressed) should work in all terminals.
* **Shift+keypress**: All characters keys (letters, numbers and punctuation) should work as expected.
* **UTF-8**: UTF-8 input should work fine in a unicode-enabled terminal emulator, but raw linux TTY may be more capricious.
* **Control codes**:
* The `key_codes` example can be a useful tool to see how the library reacts to various key presses.
* Keep in mind that if the terminal has shortcuts registered, they probably won't be transmitted to the app.
* UTF-8 input should work fine in a unicode-enabled terminal emulator, but raw linux TTY may be more capricious.
Here is the support table for input keys (All means Linux TTY and terminal emulators):
| | Key | Shift+Key | Ctrl+Key | Shift+Ctrl+Key |
|--------------------------|:----:|:----------------------:|:--------------------------:|:---------------:|
| Letters | All | All | All (except c,z,q,s,i,h,m) | None |
| Numbers | All | All | None (can crash the app) | None |
| Punctuation | All | All | None (can crash the app) | None |
| Enter, Esc | All | None | None | None |
| Left, Right arrow keys | All | VTE+Xterm | VTE+Xterm | VTE+Xterm |
| Up, Down arrow keys | All | Xterm | VTE+Xterm | Xterm |
| Ins | All | None (paste clipboard) | Xterm | None |
| Del | All | VTE+Xterm | VTE+Xterm | VTE+Xterm |
| Home, End | All | Xterm | Xterm | Xterm |
| PageUp, PageDown | All | None | Xterm | None |
| Fn keys: F1-F4 | All | None (WIP) | None (WIP) | None (WIP) |
| Fn keys: F5-F12 | All | VTE+Xterm (WIP) | VTE+Xterm (WIP) | VTE+Xterm (WIP) |
| PrtScn, ScrollLock | None | None | None | None |
