Welcome to GEOS! GEOS can work with Keyboard, Joystick, or Mouse. 

JOYSTICK/KEYBOARD:
If you don't have a joystick in Port 1, simply turn on the C64U's handy dandy keyboard joystick emulation:

a) Tap the Multi Function switch to enter the Main Menu
b) Select JOYSTICKS & CONTROLLERS
c) Set Keyboard Joystick Emulation to WASD Port 1
d) Back out of the menu and choose to save changes to flash memory

MOUSE:
To toggle the input mode to Mouse (Port 1): Press C= + i

HOTKEYS:
GEOS also supports some keyboard hotkeys. Most commands use the Commodore key C= to access functions. 
Common commands include C= + Z to open a file, C= + D to delete a file, and C= + R to reset the desktop.

Try these hotkeys:
Press [^CRSRv] to scroll the window one page down
Press C= + 1 through 9 to choose an icon
Press C= + Z to open that icon or file

Try this to open to GeoWrite:
Once GEOS has booted, press the C64U Multi-Function switch to return to the File Browser
Open the "GEOS Swap Disks" folder
Scroll down to "GEOWrite.d64"
Press RETURN and choose to Mount Disk
Press C= + A to open the disk in GEOS
Press C= + 1 to select the first icon
Press C= + Z to run GeoWrite!

Then use WASD and RETURN to move the cursor and select things! (Requires joystick emulation - see above.)

More Hotkey Commands:
C= + 1 through 0: Select an icon or file
CRSR up/down: Change page (window)
C= + Z: Open file
C= + H: Duplicate a file
C= + M: Rename a file
C= + Q: Get file information
C= + P: Print
C= + D: Delete a file
C= + U: Undo a delete operation
C= + I: Input/Printer Preferences
C= + R: Reset the desktop

Disk Operations:
C= + O: Open a floppy disk
C= + C: Close a disk
C= + N: Rename a disk
C= + K: Copy a disk
C= + E: Erase a disk
C= + F: Format a disk

So what is GEOS?

Berkeley Softworks launched GEOS (Graphic Environment Operating System) in 1986 as a disk-based graphical interface for the Commodore 64. The system brought desktop computing features to home users through pull-down menus, clickable icons, dialog boxes, and proportional typography.

Drag and drop functionality formed a core part of the user experience. Users could drag files directly onto the printer icon for immediate printing, move them to disk icons for copying, or drop them into the trashcan for deletion. This direct manipulation approach simplified file management considerably.

The file association system worked without requiring extensions or identifying headers. Double-clicking any data file would automatically launch its associated application, a capability that remains standard in modern operating systems. This seamless integration eliminated the need for users to remember specific file naming conventions.

Hardware compatibility expanded over time through various enhancements. RAM expansion modules increased available memory, while CPU accelerator cards improved processing speed. Hard drive support eventually became available, along with compatibility for numerous other peripheral devices that extended the system's capabilities.
