Summary

Maintenance release: AltGr (RALT) moves off the home/index R and U keys onto a single right-thumb key.

Changes

  • R and U — restored to plain &kp (no more ralt_mt hold-tap on the alpha block)
  • Right-thumb F12 — now ralt_mt RALT F12: tap sends F12, hold activates RALT (AltGr)
  • Behavior block unchanged: tapping-term-ms=280, require-prior-idle-ms=230, quick-tap-ms=175, flavor=balanced, no positional restriction (AltGr combos still span both hands)

Why

The two alpha-key ralt_mt instances added a hold-tap context to commonly-typed letters. Holding R or U for any reason silently armed RALT, and slow deliberate single presses occasionally felt sluggish. Moving AltGr to a thumb key — where holds are natural — removes that friction from the alpha block entirely while keeping AltGr easily reachable for accent combos like é, ó, ñ, ü.

Memory budget (local v1.4.2 build)

Right (nice_view) 269 KB / 792 KB (33.9%) 61 KB / 256 KB (24.0%)

Left flash dropped ~7 KB vs v1.4.1 from removing the two alpha-key hold-tap contexts.
