Keyboard shortcut doesn't always respect the OS keyboard layout

**Describe the bug**

On phanpy.social, with macOS + Chrome, and with a Dvorak keyboard layout, the physical `c` key is mapped to `j` by the Dovark layout. However, hitting that key doesn't cause the `j` keyboard shortcut (next post) as expected. Instead, it triggers the `c` keyboard shortcut (create a new post). Hitting `k` (physical key `v`) works as expected (previous post). Hitting `c` (physical key `i`) also works as expected (create a new post). It's only the physical `c` key that seems to do the physical keyboard shortcut rather than the layout-correct shortcut.

Holding `shift` while hitting `j` (physical `c` key) also does the create-post-in-new-window.

**To Reproduce**
1. Go to `https://phanpy.social/`
2. Hit the `j` key in Dvorak layout on macOS Chrome (physical `c` key)
3. Starts to "create post" as if I had hit the `c` key.

**Expected behavior**
I expect hitting `j` key in Dvorak (physical `c` key) to do the `j` shortcut action.
