When I click on an executable file in PCManFM (default file manager in Lubuntu), I get an “Execute File” dialog with three options (Execute, Execute in terminal, Cancel). Is there a way to set default action (e.g. Execute) in order to skip annoying “Execute File” dialog?
As a workaround, if you have the interesting file selected, pressing twice Space or Enter key will run it as you wish, as Execute is the default button, for the default action.
It is may be not a good idea to set Execute as default (by default :) as sometimes you may want to 'Execute in terminal', or simply 'Cancel' if you clicked an executable you just unzipped from the Internet by mistake.
