Here is a script to install in your Home stack if you get tired of
changing data in locked fields.  Instead of the choose field tool,
double click field, turn lock text off, click OK, choose browse tool,
change text, choose field tool, double click field, turn lock text on,
click OK, and choose browse tool, (which can get a mite tiresome), just
use Option-Click on a field (without a script in it) to unlock it, and
Command-Click to turn it back on.

This passes a mouseUp through the unlocked field because you have the
Commandkey down, which puts the text into the msg box and displays it.
The script hides the msg box, so it flashes on the screen momentarily.
This does not interfere with the normal operation of the Commandkey on
locked text items.

Hypercard could use andThen and orElse operators for it's boolean evaluations.
That or if the if statement evaluation was shortcutted by default.

This script uses a command-click on an unlocked field to lock it and an 
option-click on a locked field to unlock it.

on mouseUp
  if the optionKey is down then
    get the name of the target
    if it contains "field" then
      if lockText of it then set the lockText of it to false
    end if
  else if the commandKey is down then
    get the name of the target
    if it contains "field" then
      if lockText of it is false then
        hide msg
        set the lockText of it to true
      end if
    end if
  else
    pass mouseUp
    exit mouseUp
  end if
end mouseUp
