Keyboard shortcut for zooming in doesn't work on some keyboard layouts (e.g. de-CH)

[zeniko]

The keyboard shortcut for zooming out is Ctrl+-/Cmd+- and available on all keyboard layouts. Zooming in is however mapped to Ctrl+= which doesn't work on keyboard layouts where = is only available with Shift (my issue is specifically with the de-CH layout).

Shortcut initialization happens in TLeWithFontSize>>initializeFontSizeShortcuts. Since = isn't its own key, changing primary equal to primary shift equal doesn't work either, so as a work-around I've settled with changing the shortcut to primary shift minus which makes zooming in the inverse of zooming out for now.

Could either Ctrl+= be made work for keyboards where there's no = key or an additional shortcut be added for zooming in? Thanks.
