Add Japanese locale gestures for magnifier zoomIn (#20392)
Summary of the issue:
On Japanese (JIS) keyboard layouts, the default magnifier zoom in gesture (NVDA+shift+=) does not work. NVDA identifies keys by physical key name; on JIS, the + character is entered with Shift+semicolon (;), not with the key that produces = on US layouts.
Description of user facing changes:
Japanese locale users can zoom in with the magnifier using NVDA+shift+;, matching the physical key used for + on JIS keyboards (similar to the Windows Magnifier Win+Plus shortcut on Japanese Windows).
Description of developer facing changes:
Added source/locale/ja/gestures.ini with a locale-specific zoomIn binding.
Description of development approach:
Added zoomIn = kb:NVDA+shift+; under [globalCommands.GlobalCommands], following the same pattern as other locales (e.g. fi, it, ca) that remap magnifier zoom in while keeping Shift. The default NVDA+shift+= binding is left unchanged for users on non-JIS keyboard layouts.
