-`/mrkr`: Opens a formspec allowing you to display or delete markers. If you give this command a parameter (`h`/`here`, `t`/`there` or co-ordinates), it will set your HUD position to those co-ordinates.
-`/add_mrkr`: Adds markers. You can use `.add_mrkr x,y,z Marker name` to add markers. Adding a marker with (exactly) the same name as another will overwrite the original marker. If you replace `x,y,z` with `here`, the marker will be set to your current position, and replacing it with `there` will set the marker to the last `.coords` position.
-`/mrkr_export`: Exports your markers to an advmarkers string. Remember to not modify the text before copying it. You can use `/mrkr_export old` if you want an export string compatible with older versions of the advmarkers CSM (it should start with `M` instead of `J`). This old format does **not** work with this mod, so only use it if you know what you are doing!
-`/mrkr_import`: Imports your markers from an advmarkers string (`.mrkr_import <advmarkersstring>`). Any markers with the same name will not be overwritten, and if they do not have the same co-ordinates, `_` will be appended to the imported one.
