Running Matlab R2013B on SuSe Linux. Simulink Dialog boxes (block parameters, Mask dialog, etc.) appear in tiny and almost unreadable font. It looks like Arial 8 point font is used. Is there a way to change it?
[Edit] Here is an example:
[Edit] Tested with Matlab 2015b. Dialog Font is slightly larger, which is an improvement, but still too small for my preference. I can't find any way to configure it.

Press Ctrl and + at the same time to increase font.

Wow! This actually works! and not only in dialog boxes - seems to work across all Simulink windows (but not all Matlab windows or other applications). And Ctrl-minus decreases the fonts as expected.
Tons of thanks. Exactly what I needed!
Is this feature documented anywhere?

Open a new model in Simulink. Navigate to File > Simulink Preferences. This will open up a new dialog box. In the left hand side, the second option under 'Simulink Preferences' is 'Font Defaults for New Models'. You should be able to make changes here as needed. Just a word of caution, I am using windows. Hopefully this will also work in linux.

The preferences enable setting fonts for blocks, lines and annotations. I have set these to large enough fonts. What I'm missing is the font setting for dialog boxes - I don't see that in the preferences.
I've edited the question and added a screen clipping of the dialog box font I'm getting when double-clicking a "Constant" block... see above.

I have the same question with R2017b-trial version! Words are so tiny to see.
When I open the 'Simulink Preferences', I can only see three item under it on the left-hand side. But there is no option to adjust the dialog font size.
Please save my eyes if you can!
Thank you for any help you can provide!
