keystrokesEqual function
Compare two ParsedKeystrokes for equality. Collapses alt/meta into one logical modifier — legacy terminals cannot distinguish them, so "alt+k" and "meta+k" are the same key. Super (cmd/win) is distinct — only arrives via kitty keyboard protocol.
Implementation
bool keystrokesEqual(ParsedKeystroke a, ParsedKeystroke b) {
return a.key == b.key &&
a.ctrl == b.ctrl &&
a.shift == b.shift &&
(a.alt || a.meta) == (b.alt || b.meta) &&
a.superKey == b.superKey;
}
