The opposite problem of text entry on a constrained device is removing already filled-in values. Long URLs, or other old, pre-populated or pre-filled data may be inaccurate, and can be slow to clear.

'''Clear Entry''' functions should not be used universally, and can be dangerous as they may accidentally encourage deletion. But they should be considered for some types of fields, or forms.

principles of '''[[Cancel Protection]]'''

revert, via cancelguard/exitguard

Need an easy way to do this, as typical desktop methods are hard to do, BUT, abide by principles of mobile design and let it be undoable also. (suggest how, if not OS level, like press and hold clear after this returns it, or robust autocomplete saving). Refer to Cancel Guard (which references this!) to make sure everything is on the same page. Likely to use some of the same diagrams also. Also count clearing overall entry, selections other than text fields, whole forms, etc. Some anti-patterns, but some value.

Solution

The opposite problem of text entry on a constrained device is removing already filled-in values. Long URLs, or other old, pre-populated or pre-filled data may be inaccurate, and can be slow to clear.

Clear Entry functions should not be used universally, and can be dangerous as they may accidentally encourage deletion. But they should be considered for some types of fields, or forms.

Variations

Field level (careful!)

  • - button - features - like high speed key repeat when deleting, so you can delete a long URL field easily...

Form level (anti!)
