How to add Ctrl 5 shortcut icon in tool bar?

Hello,

I hope you're doing well, and we apologize for the delayed response and the trouble.

To add a "Ctrl" shortcut to a toolbar in Adobe Acrobat, you need to customize your toolbar by going to Edit > Preferences > General, then check the box next to "Use Single-Key Accelerators to Access Tools" - this will allow you to use a single key like "Ctrl" to access certain functions directly from the toolbar depending on the tool selected; you can't directly add a "Ctrl" button to the toolbar itself, but you can effectively create a single-key shortcut for any tool you want to use quickly.

For more information, please see this article: https://adobe.ly/4jdr1wz

I hope this helps.

Thanks,

Anand Sri.
