Shortcut in command line to navigate through command history (UP arrow) switching mac spaces

Hi,

The shortcut that I use on the MATLAB command line to navigate through the command history, the UP arrow or anything I change it to, now makes my mac switch "spaces" by one to the right.

I haven't been able to find anything online regarding this problem and would very much appreciate any help in solving it.

Thanks, William

Can you further explain what do you mean by 'mac switch 'spaces' by one to the right'? Also, what version of MATLAB are you using?

[Walter Roberson]

"spaces" is the term that was previously used in OS-X for what it now calls "desktops". The desktops are ordered linearly with one of them being active. The one before the active one in the order is "left" and the one after the active one in the order is "right". With the default keyboard shortcuts, the left one can be reached by pressing control-leftarrow and the one to the right can be reached by pressing control-rightarrow . The keypress to see the summary was formerly F10 (I think it was) but is now F3 (at least on my MacBook Pro laptop).

Thus the problem description does make sense to me. I just have no idea at the moment what could cause it.

Hi Mr. Roberson, thanks for the clarification and the great effort you have made on MATLAB Answers！

To work around this issue, the assignment of MATLAB can be changed manually as follows:

1) Right click the MATLAB icon in the OS X dock. 2) Go to "Options" -> "Assign To" with the mouse 3) Choose "none" for the assignment

After the assignment has been changed, pressing the "up arrow" does not switch desktops when working with instances of MATLAB in different desktops.

I have my MATLAB assigned to a particular desktop in OS-X Yosemite (same in the operating system before it), but with R2014a and R2013b, I have never had the up-arrow switch desktops on me, not even if I use a modifier key with the up-arrow.
