Any pushbutton (pushbutton / pushbutton-6mm) can now be driven from the
keyboard. Assign a key from the component property dialog — a keycap
control captures the next keypress (Escape cancels, modifiers alone are
rejected) — and a keycap badge next to the component label shows the
mapping on the canvas. Several buttons may share one key on purpose;
the dialog shows a hint when that happens.
At runtime a global bridge translates keydown/keyup into the same
button-press / button-release DOM events the mouse fires on the wokwi
element, so every simulation path (avr8js pin logic, SPICE-driven
inputs, the QEMU GPIO bridge, the pressed visual) behaves identically
to a mouse click. Guards: ignored while typing in inputs or the code
editor, ignored with Ctrl/Alt/Meta held, auto-repeat collapses into one
long press, and window blur releases everything so no button sticks
after Alt-Tab.
The binding is stored as the component's 'key' property, so it
round-trips through project saves and .vlx exports and is undoable like
any other property edit. Strings added to all 9 locales.
