INSERT
you can insert text from your host’s clipboard by pressing the right mouse button (default setting) or by pressing Shift + Ins. Note that this has the same effect as entering every character manually. So if you are using auto indentation in vim, this will very likely screw up your code.
To fix that, you can do the following:
Before pasting into vim, enable paste mode by entering :set paste.Press I to enter insert mode. The status bar should say -- INSERT (paste) -- now.Press Shift + Insert (The auto indentation of vim should not happen.)Press Esc to leave insert mode, and disable paste mode using :set nopaste again.
