Comment on YSK you can use custom keyboard symbols(keys), so you can easily enter symbols like αβγδ, or swap : -> ; and ; -> :

  Also, simplicity is in the eye of beholder

  I did say it was my opinion. 🙂

  i would like to understand what can you do with it

  You can have multiple functions per key, like holding a key for a longer period. It can then output something completely custom, or act as a modifier, or switch layers when held. You can also “tap dance”, meaning if you tap a key more than once you can output different things, like double tap “a” for “å” e.g. You can also tap two keys at the same time to do different things, like tap E and = at the same time for a € or something. Very powerful stuff. 👍
