[Feature] Home & End keys don't work when editing a cell

Initial checklist

• Is this really a problem?
• I have searched the Github Issues for similar issues, but did not find anything.

Problem

The problem comes when editing the content of any cell and need to go quickly to the beginning or end of its content (using Home or End keys instead of mouse). Unfortunately, the cursor does not move.

I would like that it worked as in Excel (or any other editing tool). That is, the cursor should go to the beginning or end of cell's content (using Home or End key). Also, the combination with SHIFT key should work (for selecting content)
