To program the Flirc USB dongle you'll need this (at the bottom)
The Skip 1s remote sends IR signals, be it straight to a IR receiving device (TV) or to the Flirc Dongle (which is also an IR receiver). The dongle translates this signal to a HID command. The can be a keystroke. So anything you can't do with the Skip 1s software (at the moment), you can program with the Flirc software, like long press or keyboard commands. After programming you'll need to insert the dongle into the device you're running Kodi on.
Granted, it's confusing. The Flirc dongle has built-in profiles. That why you can choose 'Flirc Kodi device' in the Skip 1s software. But not all profiles are build-in. You'll need the Flirc software to program key presses (as shown in he picture). The Flirc Software also has a Kodi profile, but it's not the same as the profile in the Skip 1s software and you'll not see changes made in Flirc in Skip and vice-versa.
To recap:
You can use only the Skip1s software to program the remote, but options are limited.
You can use only the Flirc software to program the remote for keystrokes etc. but you can't program devices like a TV.
You can use both Skip and Flirc to achieve your goals, but is has a steeper learning curve, various pitfalls and several inconsistencies between the software.
Would be nice to have a Full Keyboard profile as a Flirc device in the Skip 1s software. You wouldn't need the Flirc software, but the programmers need to iron out all its current quirks first. That however, is a long list for another topic post
