This is something I use in every transcript, in captioning and freelance.
On the broadcast side, S-DZ is defined as:
This will force whatever text you have on to the screen.
Then it will blank the screen so they won’t see the (?).
On the freelance side:
ALT U > Input.
This will make it invisible. This will not work on the captioning side.
Macro to search for (?):
ALT U > Edit.
Click on Macros.
Click on New.
Macro name: FIND (?)
Speed keys: Ctrl+Alt+/
Click on Add Command.
Hit F twice. Stop on Find.
Look at the above picture to make sure you have it correct.
User > Save Settings.
I recommend viewing how to make a basic macro and also how to make a macro from scratch. These posts will give you greater clarity on how to create macros. This FIND (?) macro is one of the more complicated ones.
