The HOME and END keys move to the top and bottom of the document instead of start or end of the current line as expected. The HOME and END keys lay dormant on the keyboard, because the need to move to the top or bottom of a document is, like -ALMOST NEVER !!!
Now, the shortcut key to the start or end of the current line in Mac OS is the CMD+RIGHT/LEFT ARROW shortcuts.
Too bad, these are not as easy to remember, oh well.
So anyway, if you’re going MAD like me trying to figure out a quick “end of line” key now you know. Hope this helps ! : )
