List of PyCharm Actions

PyCharm saves macros in XML format like the following:

<macro name="Clean Code">
  <action id="$SelectAll" />
  <action id="AutoIndentLines" />
  <action id="OptimizeImports" />
  <action id="EditorDown" />
  <action id="EditorUp" />
</macro>

I'm wondering if there's a list of actions (like EditorDown and OptimizeImports) available anywhere. I know that macros are not intended to be created by editing the xml file directly, but I'm curious :-)
