The action bar has a screen of its own now - Action bar settings, from
the app's main screen or from the button in settings. It outgrew being a
section on a page that was already long.

Two kinds of slot are yours to make. Text types whatever you wrote, and
holding it repeats. A key combination - modifiers plus a key, Ctrl+B or
Esc on its own - sends it once on a tap, and holding presses the key and
leaves it down until you press the slot again, which is how Shift stays
held for a selection.

The themed launcher icon is fixed. A themed home screen paints whatever
is opaque in the icon with its dark colour and fills the rest with its
light accent, so the old layer - a solid plate with the keys punched out
of it - came out inverted, and the lettering inside it turned into
blobs. The keys are the opaque mark now, inside a thin outline, and the
lettering is left out at a size where it was four pixels tall.

Also: on the special-keys page, "=" holds ":" - it was the one key in
that row with nothing under it.
