PhpStorm Cursor Positioning Issue Follow

Hello,

I am new to phpstorm, but this is driving me crazy.  It is allowing me to place the cursor anywhere on the page.  From there, it allows me to start typing anywhere on said page.  Also, if you are on say line 50 which is a long line of code(line 51 is a short line of code) and you press the down arrow it will go down one line at the current position and not to the end of line 51.  I really hope there is a setting to turn this 'mode' off.

Please advise. Thank You
