Customizing selection behavior

Hi,

I’m completely new to the amazing world of blender, although kind of a veteran in 3d, coming from Modo, so I’ll probably be posting a lot of stupid questions in the coming weeks.

Question number one has to do with Lasso select (ctrl+right click & drag… probably ctrl+left click & drag by default). The current behavior is, that it adds to my current selection, although most of the time, I’d prefer the tool to automatically deselect all before starting a new selection.
Is there a way to set up the lasso selection so that it would work the way I would like it to?
I find it kind of clicky to always have to press A before starting my selection, oftentimes i even forget to do so.

Thanks in advance.
Regards,
Ivan

File / User Preferences / Input
Search for lasso
Expand the Lasso Select under the 3d view category and disable ‘Extend’
Then use Save User Settings

Wow, that was quick! Thank you very much, works like a charm now.

ok, new day, new problem… What I would like is to bind the Deselect All command to Action-clicking (LMB in my case, RMB by deafault)anywhere on empty space inside the 3d viewport. I found the select/deselect toggle command in the input preferences, but I can’t seem to get it to work.
Thanks in advance!
