It would be more beneficial:
If when opening https://app.getkeywords.io/ the focus goes to the Enter the keyword
Make the TAB button work to change Country/Language
Make up/down buttons work in Country/Language dropdowns so we can select it with Enter.
Then TAB to Search and Enter for search.
In this way the search could be completely user by keyboard no need of use of mouse on that part. And it will make the search experience more faster.
