Total Commander

In some cases, it could be convenient to have one button where it would be possible to set different special parameters (variables) each time the button is used.
For example, we have a button with "%N" parameter, but in some cases we want to pass the "%P" instead.
I suggest to implement it in following way:
we already can modify the dialog by putting question mark (?) as a first parameter in Parameters button field, so when to click a button, TC asks whether to change current parameters of the button (with internal special parameters being already expanded).
If to add this dialog button which will allow to choose the other parameters (similar to "+" button in F7 dialog), it will be possible to quickly select and replace e.g. the value of "%N" with value of "%P".

Now that the specuial %B parameter is implemented, such an option to insert parameters would be useful e.g. for following case:
I use a button bar button: to create an archive with the name of file under cursor.

But sometimes I prefer file's parent as an archive name, so in this case I can use another button with "%B.zip" instead of "%O%E.zip".
Instead of having these 2 buttons I'd prefer to be able to instert the value of mentioed parameters righrt in the "Command line parameters" button's dialog (invoked by "?" mark in parameters) using a button there which will open a list of available parabeters (similar to "+" button in F7 dialog which offers a list of placeholders).

Good idea, Support+

Currently I solve such problem making a button using the Toolbar.exe from the ButtonBar eXtended 2.4 - source.
So in your example the normal click uses the filename and a Ctrl-Click uses the pathname.
