It can be done! Although slowly
and with Windows
Open "My Computer", then C:\, then WINDOWS, and finally CHARMAP.EXE. To "type", double-click each letter, hit copy, right-click a text entry and select "paste" in the contexual menu. Password entries will not let you paste, so use your browser's edit menu. Use File, Open to load webpages on browsers without a "go" button.
If you rely on Linux
, Windows telnet
pasting! Just open some textfile for the crlf
Update: It has come to my attention that you can do this much faster with xkeycaps. Telnet in, start X, export DISPLAY=:0 && xkeycaps & logout
