I'm working with a results grid for which I am adding an "alphabet filter":
The darkened portion indicates the selected letter for which to filter.
I'm attempting to find a good way to indicate how the user can "clear" the currently selected letter. My first instinct is to put an "X" symbol somewhere near the currently selected letter, but I'm worried about the size of the "X" indicator.
I'm also considering using a "clear" button immediately to the left of the alphabet but that just seems lazy/ugly.
Is there any consensus on which is a better option? Are there any other possibilities I'm not thinking of?
