Is it possible to store my email address and be able to automatically
appear in the online boxes I need to enter it into? I remember back in
the DOS days that it was something like CTRL F3.

Hello Mark800

If you only require this function in your internet browser then I
would suggest that you download and install the Google ToolBar.  This
automatically fills in certain boxes on forms you would not even have
to touch a key :-)  In addition to this it has many other useful
features including a pop-up stopper and instant access to Google.

If you require it as a function over the whole of Windows you might
find one of these programs useful (and they would also solve the
problem just for your internet browser):

If you have any further questions on this subject please ask for
clarification and I will do all I can to help.
