typing is a pretty mixed bag:
- how to enter specific characters
- keyboard hardware problems
- how to change font attributes in various software
- hot to handle various page layout and LaTeX problems
- issues with hotkeys
- how to use or accomplish tasks on data entry devices
- handling foreign languages
- typing methods and ergonomics
- auto-completion
- learning aids
- etc.
A number of these usages would benefit from a tag but a catch-all tag doesn't seem valuable. This isn't my area, so specific recommendations ought to come from people for whom the tags are relevant. I'll just put this out there and people can suggest the best resolutions in answers.
