Add a collapsible panel for sending browser-reserved key combinations (Ctrl+W, Ctrl+N, Ctrl+T, etc.) and other terminal sequences to the SSH session via mouse click. Categories: Terminal Control, Line Editing, Special Keys, Network Equipment (Cisco Ctrl+Shift+6), and Function Keys (F1-F12). Resolves #89 See also: billchurch/webssh2#481
High severity DoS via __proto__ key in mergeConfig. In practice, axios is a transitive dev dependency only (@axe-core/cli → chromedriver → axios) and is never included in the production bundle, so runtime risk to end users is negligible. Updating per SECURITY.md CVE exception to the 2-week cool-down policy.
Ctrl+B is the default tmux prefix key and also moves the cursor back one character in readline. Browsers intercept it for the bookmarks bar, so it is marked as browser-reserved.
