Understanding keyboard shortcuts in Jetpack Compose
summary
A sample app called keyboard shortcut demo demonstrates cross‑platform shortcut support by mapping a platform‑agnostic KeyboardShortcut class to Android’s onProvideKeyboardShortcuts / onKeyShortcut, iOS UIKeyCommand, and a desktop menu bar. The class uses a conflated channel and flow to publish presses to Composables; dropdown items render key labels via a custom renderer. Access keys underline one character with a regex and intercepts use onPreviewKeyEvent; iOS needs extra filtering (Alt+D inserts characters) and Android requires a Gboard workaround for dictation. The implementation compiles and runs across Android, iPad, and desktop with noted platform quirks.
