Missing keyboard shortcuts for common actions

There are no keyboard shortcuts for the common actions such as 'Highlight selected text', 'Remove selected text', 'Replace selected text'.

Due to these missing shortcuts, I have to move the mouse cursor across the complete screen to add a simple comment. All the offline PDF reader programs, especially Foxit, are handling this situation much better, but due to workflow constraints, I cannot use them. This forces me to get a repeatedly bad impression of the UX capabilities of Adobe software.
