"h"-Flag "handle"
Search Child Window
Intention
This flag is an exception. In fact it must not search the window, it will just localize the window "by handle". Of course this is a very efficient solution. Therefore if you have already localized your child-window before, keep the handle. You can keep the handle for example in a variable. Or on the stack.And then just feed it back to SCW. when you need that window again, using the "h"-flag.
As the "h"-flag does not search anything but immediately localizes the window, you should not combine it with other search flags, like "p","c","t" or these. It will just take priority and ignore these. You can combine the "h"-flag with the flags like "o","g",V" and "W". For example:
SCW.hg|123|notfound
Is completely Ok.
When using the "h"-flag with a valid child-window handle, there is no need to first use STW. to get a Top-Window. You can immediately locate a child-window. If you then need the Top-Window from that child window, you can use the GCT.-command.
' Localize by handle
STW.t|TestApp
' We grab the handle in a variable
SCW.t|button 1
HTV.$$MYC
' Later we can always get definitely this window,
' without further parameters
' No need to first localize a Top-Window!
SCW.h|$$MYC
MMV.
'
' Work with another window
STW.h|52367
MMV.
' jump immediately back to this child-window without
' the need to localize a Top-window first.

Remarks
Locating child-windows using the "H"-Flag is not a windows-search, but a direct localization.
