 ## Flow Ratio
 
+[Variable](Built-in-placeholders-variables): `filament_flow_ratio`.  
 The material may have volumetric change after switching between molten and crystalline states. This setting changes all extrusion flow of this filament in G-code proportionally.  
 The recommended value range is between 0.95 and 1.05. You may be able to tune this value to get a nice flat surface if there is slight overflow or underflow.  
 The final object flow ratio is this value multiplied by the filament flow ratio.

 If your firmware doesn't handle the extruder displacement you need the G-code to take it into account. This option lets you specify the displacement of each extruder with respect to the first one. It expects positive coordinates (they will be subtracted from the XY coordinate).

 ## Length
 
+[Variable](Built-in-placeholders-variables): `retraction_length[extruder_idx]`.  
 When retraction is triggered before changing tool, filament is pulled back by the specified amount (the length is measured on raw filament, before it enters the extruder).
 
 ## Extra length on restart
 
+[Variable](Built-in-placeholders-variables): `retract_restart_extra[extruder_idx]`.  
 When the retraction is compensated after changing tool, the extruder will push this additional amount of filament.
 
 ## Retraction speed
 
+[Variable](Built-in-placeholders-variables): `retraction_speed[extruder_idx]`.  
 Speed for retracting filament from the nozzle.
 
 ## Deretraction speed

 ## Retract on layer change

 This forces a retraction on layer changes.
 
 ## Wipe while retracting
 
+[Variable](Built-in-placeholders-variables): `wipe[extruder_idx]`.  
 This moves the nozzle along the last extrusion path when retracting to clean any leaked material on the nozzle. This can minimize blobs when printing a new part after traveling.
 
 ## Wipe distance
 
+[Variable](Built-in-placeholders-variables): `wipe_distance[extruder_idx]`.  
 Describe how long the nozzle will move along the last path when retracting.  
 Depending on how long the wipe operation lasts, how fast and long the extruder/filament retraction settings are, a retraction move may be needed to retract the remaining filament.
 Setting a value in the retract amount before wipe setting below will perform any excess retraction before the wipe, else it will be performed after.
 
 ## Retract amount before wipe
 
+[Variable](Built-in-placeholders-variables): `retract_before_wipe[extruder_idx]`.  
 This is the length of fast retraction before a wipe, relative to retraction length.

 Experimental feature: Retracting and cutting off the filament at a longer distance during changes to minimize purge. While this reduces flush significantly, it may also raise the risk of nozzle clogs or other printing problems.

 ## Z-hop height
 
+[Variable](Built-in-placeholders-variables): `z_hop[extruder_idx]`.  
 Whenever there is a retraction, the nozzle is lifted a little to create clearance between the nozzle and the print. This prevents the nozzle from hitting the print when traveling more. Using spiral lines to lift z can prevent stringing.
