How to switch to the buffer where the file with a given name is opened in Vim?

Question

Is there a function in Vim which will switch to a buffer? For example, if I know that I have the TODO.txt file open in some window in some tab, I’d like to jump to that tab and focus that window. Is that possible?

Answer 1

set swb=useopen,usetabe will set make :sb [number] or :sb [pattern] switch to an open window in whichever tab.

Answer 2

I believe it's :drop filename
