This question isn't related to TeX directly, but I was thinking about it as a total TeX newbie in the past and it still seems an interesting thought experiment. I suppose that the answer depends on which editor one uses, so I'll mention that I'm using TeXStudio.

Suppose I have defined a new command with \newcommand{\add}[2]{#1} {#2}}. When one enters the command, the interface displays \add{arg1}{arg2} and one is supposed to fill in arg1 and arg2. Is it possible to change these argument placeholders into a custom value in order to make it easier for users to understand what they're supposed to enter? For example, something like \add{entity}{title}.

  • Not a real answer since you're talking about TeXstudio, but for what is worth, AUCTeX does this by default. When you insert a supported macro or environment, you're prompted for arguments and the prompt message verbosely indicates what that argument should be. You don't have to change anything on your side.

I don't know about TeXStudio, but you can achieve this in Texmaker:

User->Customize Completion:

Customize Completion dialog box

The @ symbol inserts which serves as a tab stop. Use in the editor:

suggested commands

The downside is that it inserts this text, so you 'll have to delete it to enter your arguments:

use in editor

To give a name to an command argument in TeXstudio, you have define that command in a cwl file.

For details, see the FAQ: How does TXS know about valid commands and the definition of the CWL format in the manual.
