Mouse click

[ose159]

Hi,

i am using the PMDG 777 200 and there are some points in the screen where you can click with the mouse for example to switch on all the landing lights all togheter.

I did not find any preset to activate all of them at once but just the left, center, right but i have just a button available.

Can i assign to that button a "mouse left click" (0x20000000) ? How to do it if possible ?

Thanks in advance
