Sometimes I need to navigate among some folders. I need the "go back" in a convenient way, like "cd -". But, this is not supported in Matlab. Is there any way to achieve this? If not, a keyboard shortcut to pop up the recent directory list is OK,too.

Thank you very much.

Embarrassed, I am not familiar with Java script. Navigating among the Java script is hard and frustrating. For me, I prefer to make an own hotkey with Autohotkey for Matlab, by faking a click button on the blue arrow or "file name tab". And wating for updates of Matlab. Thank you for your kindhearted advice. @per isakson (why I can't quote your name)

There is a Back button in the Current Folder toolbox. That takes be back to the folder that was previously the current folder. Does that help or are you specifically looking for a keyboard shortcut?

Thank you for your advice. I need this. And I am just curious about why Matlab doesn't support "cd - ". It has "cd .././~" yet. Sometimes I was too lazy to move my mouse than keyboard commands, haha.

support for . and .. is present because NTFS and all Unix filesystems literally have entries named . and .. inside them. MATLAB does not need to do any special parsing for either one: it can just ask the operating system to change directory (and then query to find out where it ended up.)

There is special processing for ~ as that is not handled by the operating system. It is, however, only necessary to construct the mapping of ~ to a folder name once at startup time using environment variables HOME, or USERDRIVE and USERPATH, as changes to those are ignored (iirc).

Supporting cd - would require that cd keeps history, which it does not do at the moment. I don't think it would be a difficult change to support one level of history, but it would be different in character than what is already implemented.
