In PyCharm, how can I save just the current file?

And to get SAVE DOCUMENT to appear in the FILE menu, you need to open:

1. settings->menus
2. toolbars->main menu->file
3. Hit the + option to add a command
4. Sarch for save document and select it.

You can move it around in the menu list once it's added.

In PyCharm 4.5.4 there is a command called "Save Document". It saves only the current file.

Go to Preferences > Keymap

Search for "Save All" in the search box on the right. Find the "Save All" command, right-click on it, remove Cmd-S and add Cmd-Shift-S. It may warn you that this will remove Cmd-Shift-S from another command; click "Remove".

Search for "Save Document". Right-click on it and add the Cmd-S shortcut.

On Windows, use Ctrl-S instead of Cmd-S.
