You can set any of the preferences on that page and a few more by editing a file:
The location of the file is:
On Mac OS X:
/Users/(username)/Library/Arduino15
On Windows:
Arduino IDE 1.6.5r5 and previous:
C:\Users(username)\AppData\Roaming\Arduino15
Arduino IDE 1.6.6 and later:
C:\Users(username)\AppData\Local\Arduino15
On Linux:
/home/(username)/.arduino15 (a.k.a. ~/.arduino15)
Note that it might be a hidden folder.
- Close the Arduino IDE
- Open the file preferences.txt in a text editor
- Edit the preferences
- Save the file
- Open the Arduino IDE
They seem to have added a huge extra space at the bottom of the preferences page some time after Arduino IDE 1.6.5-r5 so you might try that version to see if the preferences page fits on your screen. It's a bit old but was a good version.
