Paste in insert mode?

While in insert mode hit CTRL-R {register}

Examples:

• CTRL-R * will insert in the contents of the clipboard
• CTRL-R " (the unnamed register) inserts the last delete or yank.

To find this in vim's help type :h i_ctrl-r

While in insert mode, you can use Ctrl-R {register}, where register can be:

• + for the clipboard,
• * for the X clipboard (last selected text in X),
• " for the unnamed register (last delete or yank in Vim),
• or a number of others (see :h registers).

Ctrl-R {register} inserts the text as if it were typed.

Ctrl-R Ctrl-O {register} inserts the text with the original indentation.

Ctrl-R Ctrl-P {register} inserts the text and auto-indents it.

Ctrl-O can be used to run any normal mode command before returning to insert mode, so
Ctrl-O "+p can also be used, for example.

For more information, view the documentation with :h i_ctrl-r

If you don't want Vim to mangle formatting in incoming pasted text, you might also want to consider using: :set paste. This will prevent Vim from re-tabbing your code. When done pasting, :set nopaste will return to the normal behavior.

It's also possible to toggle the mode with a single key, by adding something like set pastetoggle=<F2> to your .vimrc. More details on toggling auto-indent are here.

No not directly. What you can do though is quickly exit insert mode for a single normal mode operation with Ctrl-O and then paste from there which will end by putting you back in insert mode.

Key Combo: Ctrl-O p

EDIT: Interesting. It does appear that there is a way as several other people have listed.
