An upward arrow above a horizontal bar, marking a latching shift.
The glyph ⇪ marks the caps lock key, which latches rather than momentarily applying: the bar beneath the arrow is the distinction from the shift key's plain arrow.
Encoded as U+21EA UPWARDS WHITE ARROW FROM BAR, an outlined upward arrow standing on a horizontal line.
Contexts: Software
Marks the key that latches letter keys into their upper-case form until pressed again, rather than only while held.
Contexts: Software
The bar under the arrow distinguishes a latching modifier from a momentary one, which is why the shift key's arrow has no bar.
Contexts: Software
An outlined arrow pointing upward, its stem widening into a broad head, standing on a short horizontal line drawn beneath it.
The two differ only by the bar beneath: shift is momentary, caps lock latches.
