# Edit modes

Here you can decide what modes to display in the edit mode list at the bottom right corner and change some shared options.

The file [`CustomLabels.ini`](https://docs.sannybuilder.com/edit-modes/customlabels.ini) contains the list of label names and their offsets. If the disassembler finds a match between the label offset in the source file and the offset defined in the INI file it gives this label a name associated with this offset.

The file `CustomVariables.ini` contains the list of [global variables](https://docs.sannybuilder.com/language/data-types/variables#global-variables) addresses and their custom names. The disassembler uses this file to name global variables.

The file `CustomArrays.ini` contains names of the arrays in the following syntax: the first number is the global variable address which is the first element of the array, then the array size, then a custom name. It helps the disassembler to recognize [array elements](https://docs.sannybuilder.com/language/data-types/arrays#using-constant-indexes).
