No, search by pasting from the clipboard is not possible.
thank for reply.
I have the exactly site name in Clipboard. Putty hasnt a direct search, but it isnt a problem to insert a site name directly from the Clipboard.
Search site by typing part of its name is good feature. So, insert from Clipboard isnt possible.
I have more than 50 sites and I'm not good looking for it. I suggest allowing search by name, for example as in Putty.
