My daily drivers are Reviung34 and Sweep Bling MX, they are both 34 keys, they share the same zmk keymap file.
Besides the common symbols, numbers and config layers, there is a blank layer for locking purpose, during transit I could lock keyboard to this layer to avoid triggering key press, unlock (&to 0) it via combo when I want to use it.
Sweep keymap:
== layout and key index ==
