Using Ctrl+n we are effectively doing FrontEndTokenExecute["New"] and, at least on Windows, a new window has a WindowSize equal to the current Input/Selected Notebook's WindowSize.

Can Ctrl+n produce a notebook with fixed/predefined size? Is there any option for that?

This method works for things like CreateDocument etc. but not for my case.

There is also something like CurrentValue["DefaultWindowSize"] but it doesn't seem to affect Ctrl+n.

    $\begingroup$ This would be great - I hate it when the new window opens in full screen mode because I had the window I was in maximized. And I'm the type to open 20 windows in the course of perfecting a new function. $\endgroup$

  • $\begingroup$ @JasonB That sounds similar to using FrontEndExecute[ FrontEndToken[FrontEndTokenExecute["New"], "TileWindowsTall"]]. $\endgroup$

  • $\begingroup$ @Karsten7 - thanks for that, it doesn't work perfectly for sure, but at least it puts all the available windows in a reasonable space. Though if you have two monitors, both widescreen, then the resulting windows are far from ideal $\endgroup$

If you don't want to modify MenuSetup.tr you can evaluate:

 NotebookEventActions :> {
   {"MenuCommand", "New"} :> CreateNotebook["Default"]

which will add this to user's FrontEnd/init.m

"MenuCommand" example

If one feels comfortable modifying MenuSetup.tr, replacing its seventh line with

            MenuItem["&Notebook (.nb)", KernelExecute[CreateNotebook["Default"]], MenuEvaluator->"System", Method -> "Queued", MenuKey["n", Modifiers->{"Control"}]],

will result in Ctrl+n creating a new notebook with a window size of CurrentValue["DefaultWindowSize"].

    $\begingroup$ As stated in the documentation "CreateNotebook allows any notebook option to be given." Therefore, if one prefers another WindowSize, one can for example use CreateNotebook["Default", WindowSize -> Small]. $\endgroup$

  • $\begingroup$ It took me a while to find that file, on Linux it is at $InstallationDirectory <>"/SystemFiles/FrontEnd/TextResources/X/MenuSetup.tr" $\endgroup$
