The following strings have errors:

#13:
Erase and object and all its depedencies.

Should be:

Erase an object and all its depedencies.

#23:
Create a selection group. To do a selection: i. set moving object mode, ii. select a zone by shift+drag over a backgroudn area.

Should be sth. like:

Create a selection group.\n
\n
To do a selection:\n
 1. set moving object mode,\n
 2. select a zone by shift+drag over a background area.

Another problem is that DrGWizardMacroPlay for 'Execute a macro-construction' is to small. At least on my netbook I can't see the last two lines.
