Don't try to change the way keys are mapped in edit mode unless you have a good reason. It's complicated and easy to mess up. If you do make a mistake, you can go back to the default edit mode keymapping just by removing the "User Data Folder/Save/EditMode_Keymaps.ini" file. Edit Mode loads key mapping settings from "User Data Folder/Save/EditMode_Keymaps.ini". "User Data Folder" is a special name that means the folder where all your user data for stepmania is stored, the name depends on what OS you're on. See Docs/Userdocs/sm5_beginner.txt and search for "User Data Folder" to learn where it is on your OS. Entries in EditMode_Keymaps.ini set which what keys trigger an action. Any function that doesn't have an entry in EditMode_Keymaps.ini will use the default mapping. Be careful when choosing a key for a function to make sure that same key isn't already mapped to something else either in the default mapping or in the mapping you are creating. If you hold F3, you can use the Debug Menu to reload the screen while in Edit Mode, which will reload the key mapping, so you can adjust the mapping while stepmania is running. EditMode_Keymaps.ini is broken up into four sections, one for each major mode that Edit Mode can be in. The "Edit" section is for when in normal editing mode. The "Play" section is for when Edit Mode is playing back a song. The "Record" section is for record mode, and the "RecordPaused" section is for when Record mode is paused. Each line in a section is the name of the function being set, followed by "=", then the name of the key for that function. You can list two keys by seperating them with a ":". Examples: SNAP_NEXT=Key_s SNAP_PREV=Key_d:Key_v Note that you cannot change which keys need to be held down for certain things, like holding shift for rolls. Next will be a list of function names (headed by "Function Names"), then a list of key names (headed by "Key Names"), then the default key mapping (headed by "Default Mapping") as an example.

Most keys can be set with something like this: "Key_a", where "a" is the character typed by the key. This includes keys like ".", ",", and so on. For other keys, there are special names that can be used, which are listed below. "Key_." and "Key_period" both mean the same thing. Some key names have spaces in them. Key_period Key_comma Key_space Key_delete Key_backspace Key_tab Key_enter Key_pause Key_escape Key_F1 Key_F2 (Don't map F3, it's used for the debug menu, so probably won't work.)

This is because those functions aren't useful in all modes.
