Typing jumps to another line in middle of sentence

Hi hikeswiss,

Thank you for using the Apple Support Communities! For this issue we would suggest the steps from the following article that may help:

If your Mac doesn’t respond to key presses

You may have accidentally set an option that changes how your keyboard operates.

Choose Apple menu  > System Settings, click Accessibility  in the sidebar, then click Keyboard on the right. (You may need to scroll down.) Make sure Slow Keys is turned off. If Slow Keys is on, you must press and hold a key longer than usual before it’s recognized.

Choose Apple menu > System Settings, click Accessibility in the sidebar, then click Pointer Control on the right. (You may need to scroll down.) Make sure Mouse Keys is off.

Choose Apple menu > System Settings, then click Keyboard  in the sidebar. (You may need to scroll down.) Click Edit next to Input Sources on the right, then turn on “Show Input menu in menu bar.” Open the Input menu, then make sure the correct keyboard layout is selected.

Hope this helps!

Have a great day.

It seems to be a problem with the keyboard rather than with any of the software programs.

Try using an external keyboard (doesn't have to be from Apple) to veryify that. If an external works fine, the internal one will presumably need repair.
