[compsystems]

Hello hp-prime developer group

Request/Idea:
I: Pressing the [<-] key, generates a popup or menu showing:

1: Reset [current] value
2: [All]
3: [exit]

II: Type valids with [HELP] key

(INFORM cmd of the hp48/50) do this.

PHP Code:

«
  0  keyPressedOnMenu
  «
    0 'Real' STO
    1 'Complex' STO
    2 'String' STO
    3 'RealMatrix' STO

Purpose: Avoid accidental deletion of fields.

Currently pressing the [<-] key, deletes the current field of input cmd, sometimes it is uncomfortable because the [<-] key, is not visible in the menu ([edit] ... [cancel] [ok]) of INPUT and can be accidentally pressed.
