What do the shortcuts ctrl+up and ctrl+down do besides scroll up and down in the editor? In my script, ctrl+up moves the cursor to the first function definition in the file if the cursor is currently below the function. Ctrl+down again moves the cursor to the first function definition in the file if the cursor is currently above the function. Once the cursor is at the function definition, ctrl+up or down scrolls up or down a line (which is what I expect from looking at the shortcut assignments).
I just want the scroll up and down functionality. Any help? Thanks.
