 Then restart Klipper to pick up the extensions.
 
 ## To do:
-* Add virtual tools select code.
 * Add selectable automatic calculation of active times based on previous times. Ex:
   * Mean Layer time Standby mode. - Save time at every layerchange and at toolchange set to mean time of last 3 layers *2 or at last layer *1.5 with a Maximum and a minimum time. Needs to be analyzed further.
   * Save the time it was in Standby last time and apply a fuzzfactor. Put tool in standby and heatup with presumption that next time will be aproximatley after the same time as last. +/- Fuzzfactor.
-* Save pressure avance per tool to be restored on toolchange. Also between virtual tools. Check Slicer output first if this is needed or can be put in Filament custom gcode.
 
 ## Configuration requirements
 * `[input_shaper]` needs to be used for input shaper to wordk.
 
 ## G-Code commands:
 * `TOOL_LOCK` - Lock command
 * `TOOL_UNLOCK` - Unlock command
-* `Tn` - T0, T1, T2, etc... A select command is created for each tool. 
+* `KTCC_Tn` - T0, T1, T2, etc... A select command is created for each tool. 
   * `R` - Calls SAVE_CURRENT_POSITION with the variable as a RESTORE_POSITION_TYPE. For example "T0 R1" will call "SAVE_CURRENT_POSITION RESTORE_POSITION_TYPE=1" before moving. Positioned is restored with "RESTORE_POSITION" from below.
-* `T_1` - Dropoff the current tool without picking up another tool
+* `KTCC_TOOL_DROPOFF_ALL` - Dropoff the current tool without picking up another tool
 * `SET_AND_SAVE_FAN_SPEED` - Set the fan speed of specified tool or current tool if no `P` is supplied. Then save to be recovered at ToolChange.
   * `S` - Fan speed 0-255 or 0-1, default is 1, full speed.
   * `P` - Fan of this tool. Default current tool.
