Environment: Mint Linux 17 64bit (on X86 machine)
Problem: I want to register a new program - locally built so it was not registered to the alt+f2 automatically - to alt+f2 command.
Solution: Symbolic link was used. (-s option is make link to be symbolic.)
$ sudo ln -s /your/program/execution/path /usr/bin/commandname
Example: I want to register mendeley program (paper management program) as alt+f2 command.
$ sudo ln -s /home/yulistic/programs/mendeley/bin/mendeleydesktop /usr/bin/mendeley
Then, I can start mendeleydesktop by alt+F2 and «mendeley» keyword input.
