Show hidden files in cloud9.io

Question

I am developing a node.js application with cloud9 online IDE. I need to edit the .gitignore file, but I can not see it because it is a hidden file. Does anybody knows how to show hidden files in the cloud9 file tree?

Answer 1

The method described in the other answer permanently modifies the pattern for files which cloud9 will consider hidden. There is also a quick way to temporarily display hidden files.
In the upper corner of the tree there is a gear button which opens a popup with an option to show hidden file

Answer 2

Go to upper left Cloud9 menu item, then select the preferences option.

In the settings, select tree & navigate, and then you can modify the pattern of hidden files.

To show all, yo can erase all the text box, to see the .gitignore file, delete only the ".*" in the pattern. This will make the .gitignore file appear in the file tree.
