Shortcuts for indent/dedent snippet don't work in Cyrillic layouts

[webwarrior-ws]

Expected behavior: Pressing Ctrl+[ and Ctrl+] keys indents/dedents snippet regardless of current keyboard layout. Actual behavior: In Ukrainian or Russian layout nothing happens.

FYI, there are no keys for brackets in Cyrillic layouts.

I do have the same issue on my de-CH keyboard (as reported in https://github.com/feenkcom/lepiter/issues/17).

Originally, I thought I could do without, but as soon as I started producing more content inside GT, these shortcuts became a must have. So I've redefined the shortcuts in startup.st to

LeSnippetElement keyboardShortcuts
	at: #IndentSnippet
		put: BlKeyCombinationBuilder new alt shift arrowRight build;
	at: #UnindentSnippet
		put: BlKeyCombinationBuilder new alt shift arrowLeft build.

which is also consistent with moving snippets up and down (which are [secondary]+[shift]+[up/down arrow]).

Please consider at least adding these shortcuts (if not replacing the bracket-based ones) for international keyboards. Thanks.
