            Bug ID: 120206
           Summary: When switching keyboard layout, should not behave as
                    though Scroll Lock was pressed
           Product: LibreOffice
           Version: 6.2.0.0.alpha0+ Master
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
On some operating systems, namely Linux, switching a keyboard layout (e.g. to
that of another language), the keyboard Scroll Lock indicator is turned on.
This assumes its usual function is unused, and it can be cannibalized to tell
us which layout is in use.

Regardless of whether that's a good or bad idea - it is the default and
extremely prevalent among multi-layout Linux users.

Unfortunately, LO Calc (and perhaps other apps) interpret this as if Scroll
Lock has been pressed, and changes scrolling behavior - A change that is
unexpected and undesirable.

This can be addressed in several ways - either by determining such a use of
Scroll Lock is in effect, or by simply making Scroll Lock never effect
scrolling. The first option requires some work, while the second option is the
subject of bug 112876.

I would like to see the first option implemented, but even if it's the second,
the default on Linux (or on Linux with the "ledscroll(group_lock)" setting
enabled) should be for Scroll Lock to be ignored.

Steps to Reproduce:
1. Open a new calc document
2. Enter some (differing) text in cells A1, A2, A3, A4
3. Scroll around with the cursor
4. Switch the keyboard layout (Scroll Lock will now have changed from on to off
or vice-versa).
5. Scroll with they keyboard arrow key

Actual Results:
Scrolling behavior differs

Expected Results:
Scrolling behavior is identical


Reproducible: Always


User Profile Reset: No
