IDE tools menu -> Options -> Text Editor -> C/C++ -> Tabs -> Insert spaces IDE tools menu -> Options -> Text Editor -> C/C++ -> Tabs -> Keep tabs
and the IDE commands:
IDE Edit menu -> Advanced -> Tabify Selected Lines IDE Edit menu -> Advanced -> Untabify Selected Lines
VA is happy either way. But be aware that if you are using VA Snippets to insert blocks of text, we will insert them as set, so if they are filled with tabs or spaces that is what we will insert. Just something to be aware of if you encounter unexpected tabs / spaces in your editing.
