I have a long list of functions (around 50) and I would like to build a typeahead feature for it. When you press D the selection should jump to the first entry that starts with an D (for Excel it is DATE).
- What happens if I type an 'A' as the next character? Does it stay at 'DATE' or jump to the first entry with 'A'?
- If the system saves more than one character ('DA') when does it erase its memory and the user can start fresh? 200ms, 500ms?
What would you expect?
This is a screenshot from Excel, my interface looks similar.
