Using Middle-button to paste selection (Feature Request) [4]

Hello:
I want to use Middle-button to paste selection just like I use terminal of gnome in linux, I found this can improve my efficiency.
Thanks very much.

Program Ver. : Xshell 3.0

Tools > General tab > Middle mouse option

Select 'Paste the clipboard contents' from the drop down menu.

Hello:
Thanks for you reply. Pasting from clipboard means I must copy the contents to clipboad before I do this. I mean when I select texts, just push the middle-button to paste it, need not copy first.
Thanks

Tool > Options > Under the General tab

Select the "Copy selected text to the clipboard automatically" option. This way you don't have to copy manually.

Although this method overwrites the clipboard, it can work and improve my efficiency. Thanks very much for your strong support!
