Ctrl-V

In more situations than you can imagine right now, Ctrl-V places a copy of the clipboard contents into your current document or spreadsheet.

This works in Windows Explorer, most word processors, spreadsheets etc and even in dialogue boxes!

Select some text in Microsoft Word then use Ctrl-C to place a copy of the selected text in the clipboard.
Highlight a cell or set of cells in your spreadsheet and use Ctrl-V to copy the data from the clipboard.
Alt-tab into Windows Explorer (not Internet Explorer) and select a file name. Tap the F2 key and you'’ll be able to edit that filename. Use Ctrl-C to copy the file name into the clipboard. Move to a different folder, select a file and use the F2 function key to edit the file, then Ctrl-V to name the file with the name of the previous file.

Ctrl-V pastes from the clipboard even when the Edit menu is unavailable.

Paste your clipboard contents where you will.
