InstaNav Pro 作者： Sahil Kapoor

InstaNav Pro adds keyboard shortcuts to Instagram in Firefox so you can browse the feed, reels, and DMs without reaching for the mouse.

What you can do
- Up / Down — Previous or next post (home feed or reels)
- Left / Right — Move within carousels or stories
- Enter — Open the current post; Escape — Close overlay
- Tab — Open current image or video in a new tab; S — Save or download
- L — Like; C — Comment
- H — Home; E — Explore; M — Messages; P — Profile (or author of current post)
- / or Ctrl+K (Mac: Cmd+K) — Focus search
- ? — Show full shortcut list on the page

The extension runs only on instagram.com. No data is sent to any server; preferences are stored only in your browser.
