Planet scanning with a pc

You have to scan with right click until you get an anomaly, zoom in, and hit left click.

For the Nomad, hit G and then watch the meter, and then hit E when the radar detects something.

I think you have to hold right down and left click at the same time, that's what worked for me.

You can't invest some money to a cheap mouse? That would alleviate much of the issues I imagine 

I may have to get the mouse. I remapped the scanner, but the left click doesn't launch a probe. As a matter of fact, when the galaxy map screen shows what keys to use during scanning, there is no key associated with "deploy probe".

FWIW - from the main menu, if you select "Game" there's a list of other things you can access, and among them is a manual of sorts. It explains the keys/buttons/commands available.

This is what the manual says:

When an anomaly is detected, hold [alt] and use the signal UI to help you locate the anomaly.   Once discovered, press to launch a probe and find out what it is.




So, does that mean press [alt]?  that doesn't work.  I tried remapping the [alt] button, but pressing it a second time doesn't launch.  The manual usually would say something like "to activate, press [ctrl] to finish the deed" but notice the sentence I bolded doesn't show a key, it just says press to launch a probe.  and in this case, pressing [alt] a second time doesn't trigger the probe.  The key binding menu doesn't show a key for launching a probe.   Aaarrrghhhh.
