I'm putting together a script that watches for hotkeys and allows the user to paste the current GPS coordinates. Some sites (for example, wap geocaching) already let you input coordinates. In this case, one would paste longitude, press down, paste latitude, press down, and press Ok. But some sites like Google Maps, Gasbuddy, NOAA Weather, etc. do not have a direct form to enter your latitude and longitude. So...

What shortcut keys seem most useful to people? I thought of something like Alt-C (coordinates?) and it just types in the longitude, presses an arrow, types in the latitude, presses an arrow, and submits all at once. The problem is if a website requires a different order for the coordinates, or a different arrow press. So you could have Alt-X and Alt-Y which would simply paste the longitude and latitude, respectively.

What do you think: what is easiest to use / most useful? Or other suggestions?
