I'm not sure how to best describe it, but basically when you press a letter key, it will jump to the filename starting at that letter, right? Starting search.
I believe it was possible until recently to keep pressing that key, and WinScp would iterate over all files starting with that letter/symbol. But in newest versions you have to press the key, and then TAB, if you want to iterate. Which is often times confusing, moreover when TAB has other purposes (most importantly switching panes).
Is it possible somehow to return the old behavior? I couldn't fine anything in the options.
