Hello,

Thank you for your inquiry.

Regarding the features you mentioned, "Type A: Control + F to access the Find What function" and "Event: Keydown or Keypress", these are currently not supported. Could you please provide more details about the specific effects or functionality you would like to achieve with these three features? It would be greatly appreciated if you could also attach screenshots demonstrating the desired effects. This will help us better understand your requirements and develop the features that meet your needs.

Sincerely,

We use keyboard shortcuts a lot to search for text within a document, especially documents with many pages.
In any case, we are using the mouse in the search box. It works well.
Please try to include keyboard shortcuts in future versions. This way it will be similar to Adobe Reader.

Hello,

Thank you for your response.
I have added your request to include a feature similar to Adobe Reader's "Find Text" functionality via the Ctrl + F keyboard shortcuts into our product upgrade system. The tracking number is SPIREPDFVIEWER-624.

Additionally, could you please confirm your project type? Is it WinForms?

Sincerely,
Amy

Hello,

We made a demo that simulates the "Ctrl+F" text search functionality found in Adobe Reader. Please download it from the link,
https://www.e-iceblue.com/downloads/attachment/WindowsFormsAppCase624.zip.

Instructions for Use:
1. Launch the project and open a PDF document.
2. Press Ctrl+F on your keyboard. The search dialog will automatically appear, allowing you to enter text and test the functionality.

We look forward to your feedback on the test results.

Sincerely,
Amy
