wanted software feature

– a clickable {ENTER} icon, so that after filling in the search box (such as that in WordPress), I can click on the {ENTER} icon next to the search box, instead of having to take my hand off the mouse in order to manually press the {ENTER} key.
(I’m using curly braces because WordPress goes haywire (yes, HTML syntax, I know) if I use angle brackets. WordPress could enhance user-friendliness by filtering or warning about this. It could alert new users to its ‘reserved word’ list upfront.)
