Right clicking on any cell pops up an edit menu that you can use to quickly Cut/Copy/Paste
a cell.
In the Project view spreadsheet, this operates slightly diffferently than in other
spreadsheets
Copy
The right click
menu has only a copy and paste option...but in other sheets such as User
Sheet1, the full complement of edit options is available.
Cut/Copy/Paste
Cutting or copying
a cell gives you the opportunity to paste it into another cell, as straight
text ... or... to copy a link to it using "Paste link".
Paste Link
Pasting a link means
that even if the cell is in another spreadsheet, any change to the value
of the original cell will show itself in the cell where you paste a link.
You'll notice that
pasting using "Paste link" causes a formula rather than a value to be
shown in the cell.
Clear
Clearing removes
the contents of a cell and any formula that might be contained in it.
