??? The /, *, and - keys don??™t actually send a button click; they are used to select
which mouse button will be simulated by the 5, +, and 0 keys. Pressing / will
select left button clicks; pressing * will select middle button clicks; and pressing
- will select right button clicks. The selected button remains in effect until a new
one is chosen.
Microsoft Windows and Mac OS each provide a similar mouse keys
capability, but use a different hotkey sequence to enable/disable it.
In addition to rescuing mouse users when the rodent is uncooperative, mouse keys
can be used as an accessibility tool, enabling the mouse pointer to be controlled
using a mouth stick or a headpointer, or typing aid.
