 ----
-Expand a power of a product:
+Invert indices of some expression
 <sxh groovy; gutter: false>
-def t = '(a*b*c)**d'.t
+println InvertIndices >> 'A_mn'.t
-println PowerExpand >> t
 </sxh>
 <sxh plain; gutter: false>
-   > a**d*b**d*c**d
+   > A^mn
 </sxh>
-----
-Expand with respect to ''a'':
 <sxh groovy; gutter: false>
-def t = '(a*b*c)**d'.t
+println InvertIndices >> 'A_mn*(p^m + q^m) + T_n'.t
-println PowerExpand['a'] >> t
 </sxh>
 <sxh plain; gutter: false>
-   > a**d*(b*c)**d
+   > A_m^n*(p^m + q^m) + T^n
 </sxh>
 ----
-Expand a square root:
+Invert only indices of certain type:
 <sxh groovy; gutter: false>
-def t = '(a*b)**(1/2)'.t
+println InvertIndices[LatinLower] >> 'T_ABmn'.t
-println PowerExpand >> t
 </sxh>
