Vim commands for copying to system clipboard but text does not show up in Clipman

[Philip Rhoades]

People,

In Vim, these commands are supposed to copy text to the system clipboard 
- but the text does not show up in Clipman:

"+yy

"*yy

- why doesn't this work?

In fact, rather than copying the current line as above, I want to copy 
the text of a whole file which is not conveniently done by clicking and 
dragging the mouse . . but I can't even get it to work on one line . .

Thanks,

Phil.
