Key	Action
↑ ↓ j k	move
→ ←	expand / collapse (tree)
space x	toggle option
a	toggle all (tree)
i	tool info (description, homepage, install command)
enter	confirm / continue
1–5	jump to action (welcome)
esc	back
q	quit (confirm dialog)
Ctrl+T	cycle theme
Ctrl+C	force quit

Notes

• q always opens a confirm dialog so you don't lose progress mid-install.
• Ctrl+C is hard-quit; the installer process keeps running detached.
• 1–5 numeric jumps only fire on the welcome screen.
• The footer of every screen shows the relevant subset of keys — no need to memorise the whole table.

If you'd like to rebind any of these, open an issue on GitHub — we're tracking demand before adding a config field.
