I've been creating Custom HTML Prompts since around 2015, if memory serves.
It just dawned on me that almost all of my Custom HTML Prompts call window.KeyboardMaestro.Submit() to close the prompt.
And I believe it's quite possible I've been inadvertently setting tons of global variables because of this. From the wiki:
| Function | Purpose |
|---|---|
window.KeyboardMaestro.Submit(buttonName) |
submit the form and write the Keyboard Maestro Variables |
As an example, I ran my "Variable Inspector Prompt" after running a Custom HTML Prompt I've been working on, and here's the global variables I accidentally created:
EDIT: I guess these variables only get created if I have HTML elements with the "name" attribute set, which I don't think I use a whole lot. The reason it's used in this Custom HTML Prompt is because I used ChatGPT to create the form dynamically, and it decided to set the name.
But having said that, I use VIP to check another prompt, and it sets some global variables also.
Crap. Looks like I've got a lot of work ahead of me to track down this kind of stuff.
