writing::begin records the owner's focus, the mind map's or the tool
layer's, through forms::Editing::returning. The field keeps its words on
Enter's release and drops them on Escape, and both hand focus back, so
the map's arrows and the board's Backspace work at once after a write.
Only the bar fades now, so the caption stays while the controls rest, and
the caption chip can shrink, so a long line wraps inside a narrow player.
A focused media button keeps Space to itself, since gpui presses it on
the release. The player and the strip let Command and Control letters
pass. The scrubber's tip splits the free width by the pointer's share and
stays over the track at both ends. An inline edit's label gives way with
an ellipsis beside fixed parts.
The player is a Tab stop only when a key does something, logs its
captions, keys its fade by its own id, and logs a failed wake.
Scrubber shows what has loaded, what has played and its chapters, names
the time under the pointer, seeks by press and gpui's drag, and steps by
the slider's keys; over_media lights it for a dark layer. VideoPlayer
shows the host's frame in its shape with a caption and a control bar over
it: the scrubber, play, the time, speed, captions, picture in picture and
full screen, each only with its handler; the bar rests after a still
pointer while it plays, on one wake from the executor's timer. Keys:
Space and K, J and L, the arrows, C and F. VideoThumbnailStrip lays frames
along the length under a playhead with a trim whose handles drag and whose
ends I and O set. SubtitleEditor edits cues in place: times as mm:ss.mmm,
kept in order, a time that does not read kept out with the reason shown.
InlineEdit is a Tab stop with the ring; it hands focus back after Enter or
Escape and keeps its text on Enter's release. overlays::media_button is
shared by the lightbox and the player's bar.
