# Steps to reproduce the problem:
1. Implement FindBar, including Find next / Find prev buttons

# What is the expected behavior? (add screenshot)

This might be intentional but seems a bit off. The PDFFindBar findPreviousButton / findNextButton should raise an event with options that can be passed directly to PDFindController.executeCommand

What went wrong? (add screenshot)

PDFBar raises an event on the EventBus which looks like this;

`this.eventBus.dispatch("find", { query: "hello",  ... type: "again" .... });`

PDFFindController expects;

`pdfFindController.executeCommand("findagain", { query: "hello" });`

Which means you can't just pass the options through because the cmd doesn't match. Is there a reason PDFFindController doesn't just accept the following?

`pdfFindController.executeCommand("find", { query: "hello", type: "again" });`

Seems like it should work this way?

Thanks
