# Cesium



Cesium is a shell for the TI-84 Plus CE / TI-83 Premium CE calculators.



![screenshot programs](https://github.com/mateoconlechuga/cesium/blob/master/screenshots/screenshot_prgms.png?raw=true)

![screenshot apps](https://github.com/mateoconlechuga/cesium/blob/master/screenshots/screenshot_app.png?raw=true)



Cesium is installed by running the `CESIUM` program.

This creates an application that can be accessed via the `apps` button.

The application cannot be transferred to other calculators, however the

installer can be used instead.



A video showing off various features is available [here](https://youtu.be/hZDzV1CDN3k).



## Navigation



Cesium supports alpha search for programs.

Use any key with the green text above it to immediately switch to the programs

starting with the corresponding letter.



| Combination     | Action                   |

|-----------------|--------------------------|

| `2nd` / `enter` | Run, select              |

| `alpha`         | Modify variable settings |

| `zoom`          | Edit BASIC program       |

| `y=`            | Create new BASIC program |

| `graph`         | Rename program / appvar  |

| `mode`          | Enter settings menu      |

| `arrow keys`    | Move places              |

| `green letters` | Alpha search for program |



## Shortcuts



Shortcuts are available from outside the Cesium application.



| Combination    | Action                                                 |

|----------------|--------------------------------------------------------|

| `on` + `prgm`  | Launch Cesium Application                              |

| `on` + `stat`  | Power down with password on wake (No Default Password) |

| `on` + `graph` | Open label jumper in TI-Basic Editor                   |

| `on` + `8`     | Backup RAM from TI-OS                                  |

| `on` + `5`     | Remove latest RAM backup                               |

| `on` + `2`     | Restore RAM from latest backup                         |

| `on` + `sto->` | Activate dark mode (inverted colors)                   |

| `on` + `ln`    | Activate normal mode (uninverted colors)               |



The RAM backup is performed by copying RAM contents to flash memory, so if

you are concerned about flash wear, please moderate usage.



## USB Support



Cesium has support for launching and transfering files on FAT32 formatted drive.

Future additions may be added depending on reported usage and feature requests

in the issues board on GitHub.



To transfer a variable from the drive to the calculator, use the `prgm` button.

Running a program from the drive directly may not work -- and may crash your

calculator if the program does any of the following:



* The program requires subprograms and/or AppVars in order to run.

  You must transfer all subprograms/AppVars to the calculator.

* The program uses an outdated compression mode for assembly and C applications.

  There is no way around this other than updating the application or transfering

  the program to the calculator.

* The program modifies itself at runtime. This only applies to rare assembly and

  C applications, and usually will never be encountered.

  Transfer the application to the calculator.



To avoid crashes it is recommended to simply transfer the file with the `prgm`

button instead.



## Uninstalling



To uninstall Cesium in the event a new version is warranted, press

`2nd` + `+` + `2` + `1` and delete the Cesium application and AppVar.

You can also delete the Cesium application from within Cesium.
