My question stems from a piece of JavaScript I wrote for the desktop which uses a ctrl-click to activate a certain feature. Now that I'm thinking of porting to mobile, I can't conceive of how to translate this to mobile. But the question I'm asking here is at a higher level: Does UI design for mobile require an (almost) totally different mind set / set of design skills? Is the best answer that I really need to take a course or find / hire an expert to figure out how to design for mobile?
Thank you for your insights on this
