Switching between open files in editor by searching

43 views (last 30 days)
I know this has been asked before, but among the questions I found, no one mentioned the already implemented search which is the closest match.
I want to quickly switch to an open file in the matlab editor by starting to type the name of the file, e.g. "myFu" would suggest "myFunction.m" and any other matching "myFu*". I find this functionality when the file "tab-bar" on top of the editor is full, and the dropdown menu for selecting files is displayed. This dropdown menu has the search functionality that I am looking for (see attached imaged). I find this search only available when the file-tab bar is full. This is ok as the need for a search is often related to many simultaneously open files. My question is:
Is there a action for this search which i can bind with a shortcut?
(I am familiar with the "Find files" functionality and "Ctrl + Page Up/Down". I am currently on windows and running R2020b Update 5)

There is an API you could potentially use for this sort of task. I have my installation of release R2019b open, so I'll just open a couple files. The getAll function lists all files open in the Editor.
>> D = matlab.desktop.editor.getAll
D =
1×3 Document array with properties:
>> {D.Filename}.'
ans =
3×1 cell array
{'C:\Program Files\MATLAB\R2019b\toolbox\matlab\general\bench.m'}
{'C:\Temp\example300062.m' }
{'C:\Program Files\MATLAB\R2019b\license_agreement.txt' }
This is one MATLAB function file included in MATLAB, one MATLAB code file I created, and one plain text file. The getActive function lists just the one that is the active document. In this case that's D(3).
>> A = matlab.desktop.editor.getActive

Thank you Steven. I second what Mario said. This was neat. I will dig into the API and see if I am able to come up with something which satisfy my desire. I will leave the question open for another day to see if there is any more suggestions.
