You can start a document, like this:

Remarks
Technical remark: EXR. uses Create-Process-FindExecutable-Technology and is compatible with other commands that use this technology.
EXR. can be blocked by a process that it has started. If this turns to be a problem, choose EXA. or EXF. as alternative.
Limitations:
There may be cases where EXR. can not deliver the proper PID/ TID. This depends on the target application, and may be influenced by the fact, if the target application is already running.
