"Jarvis import library foo" - could be said from anywhere in file
"Jarvis jump to file bar.c"
"Jarvis declare var current temperature equals zero" - var currentTemperature = 0
"Jarvis write for enumeration on var word over var name list"
"Jarvis build and run" or simply "Jarvis run"
By the way, I know many people don't like to talk to a computer, can't imagine how it could be faster than typing, etc. However, I believe that once an assistant is done right, more than a few people would be converts.
