How to create a macro that allows me to run the following key combination CTRL + SHIFT + Letter
I had an app, in this app I made a button to change language, but I need that inmediatly someone press the button, a triggers will fire doing the macro to block all the fields....
I don't understand what's the problem. Your "Button" to change the language is the "trigger" itself - buttons run Actions and/or Macros.
If you mean that your Language is a Variable and a "button" is an Input Box, then you can trigger your macro based on a Variable. Or, if it's a Field, - than based on a Field. Both of those triggers can be defined in "Document Properties", "Triggers".
I also didn't understand what you mean by "block all the fields"...
