Steps to reproduce: 

1. Use Chrome without extension, or headless mode.
2. Use the press key combinations Shift+End and Shift+Home in a coded step and be sure to set focus to a text field. 
   

   ActiveBrowser.Desktop.KeyBoard.KeyPress(Keys.Shift | Keys.End);
   ActiveBrowser.Desktop.KeyBoard.KeyPress(Keys.Shift | Keys.Home);

Expected: The combination selects the text in the field

• if the cursor is at the begining of the line use Shift+End;
• if the cursor is at the end of the line use Shift+Home;

Actual: The cursor only moves without selecting the text. 

Workaround: Use the key combination Shift+A to select the text.
