Commands that only affect the local debugger

When doing remote debugging, some commands affect only the local debugger (the debugger on which the command is typed). Examples are:

.wtitle
.cls
.browse
.cmdtree

At the moment these are all looking like UI related commands. Are there more commands that are only executed on the local debugger?

My research effort:

I am aware that this is asking for a favorite external tools or reference. So if you really think this is off-topic, then vote for close.

Still not a complete list, but many commands that are not scriptable (MSDN) are affected:

.lscrfix // works on remote client only
.lsrcpath // works on remote client only
.open 
.write_cmd_hist // writes local history only
.beep
.cls
.hh
.remote // Does not work in WinDbg anyway

However, the following ones from the list seem to work:

.idle_cmd
.restart

Regarding .write_cmd_hist: If you want to keep all commands executed during the debug session, it seems good to open a log file (.logopen) at the beginning of the session.

All debugger processing, including all extension execution, is done in the core debugger process. So 99+% of commands all need to go to the debugger engine (the initial debugger instance) The only commands that run only on the remote debugger are indeed a few UI related commands.

I will call out one pair of commands that is interesting on this topic which is the mostly commonly used remote debugger:

.srcpath sets the "source code path" in the debugger engine. This is where the debugger engine will get source information from if it's needed - for example, if a debugger extension wants to get to the source code.

.lsrcpath (l - for local) sets the "source code path" in the remote debugger. This path will be used in windbg (and cdb\kd also) to pull up source files in the UI.
