• I have searched for my feature proposal and have not found a work-in-progress/duplicate/resolved/discarded issue.
• This proposal is a completely new feature. If you want to suggest an improvement or an enhancement, please use this template

Describe the new feature

We could use the Tab and Shift + Tab to navigate but we could use:

• Keyboard shortcut (like a browser's default shortcut to navigate in pages with: CTRL + Numbers)
  (these should show as hints when hovering over action or buttons in general)
• Search keyboard shortcut in placeholder text as well as a hint when hovering over the search button
• Ability to modify the default keyboard shortcuts

Describe how this new feature could help users.

Navigating with a proper keyboard shortcut is really helpful and efficient especially when the user have the ability to modify the said shortcuts to their liking.
