I believe it stems from the practice on some (older?) keyboards of
printing a pair of arrows on the `tab key', one pointing each
direction, mimicking the placement of (for example) `!' over `1' on
the US-qwerty keyboard.
A little web searching suggests that it originated in the early days
of X:
There is no universal standard for "backward tab" in the X
Window System. On some systems shift+tab gives the keysym "ISO
Left Tab", on others it gives a private "BackTab" keysym and
on others it gives "Tab" and applications tell from the shift
state that it means backward-tab rather than forward-tab. In
the RFB protocol the latter approach is preferred. Viewers
should generate a shifted Tab rather than ISO Left
Tab. However, to be backwards-compatible with existing
viewers, servers should also recognise ISO Left Tab as meaning
a shifted Tab.
That same web searching also suggests that Emacs customization is the
most common source of `caring' about iso-lefttab in the present.
Hope this helps,
*Chad
