ideally not full on editors e.g
|
|
|
|
|
editor-split
|
|
|
|
|
|
|
|
|
|
highlight could start as
|
|
|
|
|
x use a jxr command to pre-select an existing jxr snippet (already exists somewhere in past work, at least for classes...)
|
|
|
|
|
x place a cursor e.g | at the beginning of the snippet copied in the feedback HUD
|
|
|
|
|
x moving the index along the x axis moves the cursor within that snippet on HUD
|
|
|
|
|
x pinching starts the selection, all characters within that selected are bolden
|
|
|
|
|
x if not (yet) supported by troika then consider another color, e.g unselected text as white, selected as grey
|
|
|
|
|
x releasing the pinch complete the selection
|
|
|
|
|
new affordance can thus be proposed as jxr snippets applying not to the entire jxr snippet pre-selected but selection only
|
