Help regarding few options.

This may have been already discussed but wasn't able to find out so asking here.

1. How to be in insert mode by default when pressing a to add a file or dir?
2. How to perform search in preview window by pressing /?

[niksingh710]

3. How to make that new file created by a is focused?

I expect it to open the test file as soon as creation

Ah, that's a bit too difficult currently.

Wait patiently for #1340 and you'll be able to do that.
