A leftward arrow meeting an upright bar, marking a jump to the start.
A left-pointing arrow stopping against an upright stroke marks the home key, which moves the cursor to the beginning of a line or document rather than one character at a time.
Marks the key that moves the insertion point to the start of the current line, or to the start of the document when held with a modifier.
Contexts: Software
The upright stroke reads as the boundary being travelled to, which is why the end key's stroke sits on the opposite side.
Contexts: Software
A left-pointing arrow whose head stops against a short upright line at the left, so the stroke reads as travel arrested at a boundary.
Both are built from arrows, and both are used in software contexts.
