Is it at all possible to have the Tab key insert 4 spaces in the question/answer edit area, instead of moving focus to the next control?
When writing code in questions or answers I could really use such functionality, especially for hierarchically indented code, like this:
codecode codecode codecode codecode codecode codecode
What I usually do is copy 4 spaces and then paste them over and over again, but using Tab is more natural (I actually do it by mistake quite often).
I think the usage of Tab for moving focus while editing a question/answer is minimal, and its benefits are insignificant versus the benefits of allowing Tabbed code.
A "neater" feature will be to push not 4 spaces but the differences between the next multiple of 4 and the current amount of spaces in the line (e.g. if I pressed once on space and then Tab, the Tab will insert 3 spaces, like "real" tabulation)
