Expected behavior: Assigning <COMMAND>+R (Apple's command key and then the letter "R" key at the same time) to a working macro in LO 7.1.5.2 (for macOS 10.15.7) should trigger the macro when <COMMAND>-R is pressed.

Actual behavior: paragraph is aligned right.

Steps to reproduce:

1. Open a new Writer document.

2. Record a macro (e.g., to change the color of selected text to Red), save as "Red", and confirm that it works by selecting some text (e.g., black text) and running macro Red. Watch the text turn red. Yay.

3. Customize <COMMAND>+R to LibreOffice Macros > MyMacros > Standard > Module1 > Red using the Customize dialog. For extra giggles, be sure to customize Right (the RightPara one) to something else, like <COMMAND>+].

4. Select some text and type <COMMAND>+R: watch the paragraph in which the selected text is located shift to the right and NOT change to red-color text.

5. Tear your hair out for a bit. Recheck your various settings. Weep maybe. Then resign yourself to the fact that <COMMAND>-R is hard coded to RightPAra in LO 7.1.5.2


Comments 
(1) macOS 10.15.7 does NOT reserve <COMMAND>+R to this behavior.

(2) Above behavior is reproduced in LO 7.1.6.2.

(3) It IS possible to assign macro "Red" to another key, such as <CTRL>+R.

(4) I would love a list of all hard-coded keyboard shortcuts in LO, and for the customize dialog to automatically gray these out, or otherwise indicate that their settings will not be honored.
