// - Added the following to each key's symbols[Group1] definition: `repeat=true`
// - The lv5 mod should be eaten up by xkb but isn't. Must manually clearmod it from all necessary keys.
// - The first 4 states are defined as `any` (a synonym of `NoSymbol`) to pass-through any existing ones.
// - KDE seems to have a problem with key redirection. Doesn't KDE respect `clearmods`?
// - Example: If Ext+Backspace is `Pause` and Ext+O is `Backspace`, KDE may wrongly send `Pause` for Ext+O.
// - As a result of this problem, the Extend mappings for Backspace and Enter are by default disabled now.
