20140	JOSM inconsistently respects remapped macOS modifier keys	derickson.e@…	Stereo	"==== What steps will reproduce the problem?

1. In macOS, go to **System Preferences** > **Keyboard**, then click **Modifier Keys** in the lower-right-corner
2. Switch the **Option** and **Command** keys, then close all options dialogs
3. In JOSM, select a feature, then press **option+A** using the newly-designated **option** key

==== What is the expected result?

All JOSM shortcuts, whether default or modified by me, should use the modifier key assignments I have set in the Mac system keyboard preferences.

==== What happens instead?

JOSM respects the system Modifier Keys settings inconsistently. With the above-pictured system settings, **cmd+A** performs ''Select All'' as expected, but **option+A** to ''Add Tag'' does not work. Neither do any of the toggle layer shortcuts, **option+1-0**. However, I can still hold down **option** while in ''Draw nodes'' to start a new way at the last node, and **option-J** still works to ''Disconnect node from way''. It does not seem to matter if I use the default shortcut or if I change it.

==== Please provide any additional information below. Attach a screenshot if possible.

When using a keyboard designed for Windows with a Mac computer, the operating system will interpret the **Windows** key as the **command** key. Unfortunately, this results in the **command** and **option (alt)** keys being swapped from their positions on a Mac keyboard, which causes problems with muscle memory when switching between keyboards. (On a Mac keyboard, the left-to-right order would be **control - option - command**; on a Windows keyboard the order is **control - windows - alt**.) The Mac operating system provides a way to mitigate this: using the ""Modifier Keys"" pane in the system keyboard preferences, the user can control what each modifier key is interpreted as. To maximize muscle memory across different keyboards, I have used this setting so that the modifier key order of my Windows-designed keyboard matches the Mac default:
