Maya MEL commands and procedures

How to find the MEL command Maya runs when you click a menu or button? Sometimes Maya doesn't explicitly display the MEL command that is executed when you click on a GUI element.

Here are a few tips:

• In the script editor go to History and enable Echo All Commands.
• Try and look in Window -> Settings/Preferences -> Hotkey Editor (The hot key editor contains a long list to MEL shortcuts!)
• The hard way: go to C:\Program Files\Autodesk\Maya2020\scripts and look for the menu names directly into Maya's code. You can use a grep command or open every script file into your favorite IDE (Vim, QtCreator, Visual Studio..)

Here is some procedures I had to look up by myself:

Mesh Display

In Maya GUI: Mesh Display -> Toggle Display Colors Attributes
MEL equivalent: toggleShadeMode();

Modify

In Maya GUI: Modify -> Paint Attributes Tool
MEL equivalent: ArtPaintAttrTool();

Modify -> Evaluate Nodes

In Maya GUI: Modify -> Evaluate Nodes -> Evaluate All
MEL equivalent: EnableAll();

In Maya GUI: Modify -> Evaluate Nodes -> Ignore All
MEL equivalent: DisableAll();

---

In Maya GUI: Modify -> Evaluate Nodes -> IK Solvers
MEL equivalent: setState iksolver true/false;
