When the editor has multiple selections (“multi-cursor mode”), tab autocomplete gets in the way and usually doesn’t work as expected. When a user creates multiple cursors, they likely want to do something specific and precise. In my case, I frequently want to indent multiple lines with tab.
It seems not to be possible to re-bind the “cursor autocomplete” action from “tab” (see this issue) so there’s really no way to do multi-selection indentation without disabling cursor autocomplete.
My preferred solution would be an option to disable cursor tab autocomplete when the editor has multiple selections/cursors.
Note that this issue is very hard to Google because it involves multiple cursors for the cursor IDE and even the best search is just never going to surface the right thing.
I opened this similar issue a few months ago but I am re-posting in an attempt to make this issue more Google-able for the above reason.
