Selecting Text with Mac OS High Sierra

Hello all, I recently upgraded to High Sierra and have noticed one thing when trying to select texts. I have only tried this in text edit. In previous versions of the Mac OS I could use voiceover to select line by line. This was accomplished by starting at the beginning of the line, holding the shift key and pressing the down arrow. Each line would be selected for editing as long as you held down the shift key and pressed down or up arrow to select or unselect lines. In high Sierra this seems to no longer be the case. Am I going crazy and doing something wrong or have they gotten rid of this feature? Thanks in advance for any help or suggestions.
