Description Mike FABIAN 2017-01-19 06:24:11 UTC 
The problem happens only when the program typed into supports surrounding text.

For example, when typing into gedit (or any other gnome program), this problem occurs.

In gedit (and most other programs), the Left, Right, Backspace, and Delete
keys have special functions when used together with modifier keys.

For example, Control+Left moves the cursor one word to left.
Control+Backspace removes a whole word to the left of the cursor.
Shift+Left marks a region in gedit (gets a blue background) and
that region can then be removed with Delete or Backspace.
Alt+Backspace exchanges the two words left of the cursor. Etc. ...

So in all these cases, reopening the preëdit does not work the
same way as when Left, Right, Backspace, or Delete are used to without
the modifiers. 

As the behaviour of these key combinations is not 
exactly the same in all programs, it is not possible to reopen the
preëdit correctly in all programs. Therefore, better don’t try
to reopen the preëdit at all when Left, Right, Backspace, or Delete
are used with any modifier (except CapsLock which does cause no such
problems).
