Keyboard-Layout – How to Switch Between Keyboard Layouts with a Shortcut Like on Windows

Ubuntu 17.10 and newer (GNOME Shell)

From this answer: After adding the desired languages (by navigating to Settings -> Regional & Language), you can use the default keyboard shortcut which is Super+Space ("super" is another name for the Windows key), or you can click on the top bar menu:

Ubuntu 13.10 to 17.04 (Unity)

As of Ubuntu 13.10, it is now called Text Entry Settings instead of Keyboard Layout

It can be reached through either of these methods

1. Going through System Settings -> Text Entry
2. Using the App Indicator as shown in the screen-shot below.

Ubuntu 13.04 and older

Seems you forgot an important step.

1. Download Hebrew language support. You can do this from the Install/Remove Languages section of "Language Support".
2. System Settings -> Keyboard Layout -> "+" -> "Hebrew" -> Add
3. System Settings -> Keyboard Layout -> Options -> Keys to Change Layout -> mark [alt]+[shift] (this step is optional, only if you want that custom keyboard shortcut)

An icon like this should appear in the upper-right after step two:

my approach towards this problem would be assigning a combination of keys (via keyboard shortcuts) for either using loadkeys/setxkbmap. Although, you might want to revert back to last used layout after using 'the special one', thus you might need to write a bash script for that.
