Phil,
F10 looks like it's set up to add the current character under the
cursor to the '/' register, so if you have "abcdef" on the screen and
hit F9 on the first character and then F10 on each subsequent one,
you'll get "abcdef" in the / register (this is because you're using .=
instead of = after "let @/".
.~\\ is a list of 3 characters ( '.', '~' and '\', the latter of which
is escaped for the string) that you're passing to the escape function
so that it will prefix them with a backslash.
As to why you have these mappings, no idea I'm afraid! If you don't
use them ever (which I can only assume is the case since you don't
know what they do), it might be a good time to delete them.
F10 will be opening the file menu on the xfce4-term because the
terminal window is presumably intercepting F10 before it gets to vim.

I didn't get very far doing a lot of Googling, but from
experimenting with them I found F9 puts the current character under
the cursor into the "/" register but F10 opens the file menu on my
xfce4-term ! What is:
'.~\\'
supposed to do?
That's the parameter to the escape() function that you're calling.
It looks like <f9> captures the character under the cursor; escapes
periods, tildes, and back-slashes; then assigns it to the current
search register. The <f10> does the same thing except it appends
rather than assigns to the search register.
I'm not sure WHY this would be helpful, but apparently you found it
so at one time :-)
Thanks for all that - I understand it all now but it still does not
trigger any memories of what I used the fns for! . . they must be from
many years ago . . or else Alzheimer's is setting in faster than I
thought . .
Regards,
Phil.
