[BUG] Help dialog cant be opened

[groutoutlook]

Description

• help_toggle uses ? in default-keybind.toml, but when pressing ?, the keybinding parser never matches and the help dialog never opens.

Environment

$ rustc --version
rustc 1.93.0 (254b59607 2026-01-19)
$ fastfetch -l none
OS: Windows 11 Pro Insider Preview (25H2) x86_64
Kernel: WIN32_NT 10.0.26300.7674
Shell: PowerShell 7.6.0
WM: Desktop Window Manager 10.0.26100.7541
Terminal: Windows Terminal Preview 1.24.3504.0
CPU: 12th Gen Intel(R) Core(TM) i7-12850HX (24) @ 4.80 GHz
Memory: 20.12 GiB / 31.69 GiB (64%)
Swap: 1.26 GiB / 23.00 GiB (5%)

Steps to reproduce

0. Run the app.
1. Press ? (shift-/) from the main view.
2. Help dialog does not appear.

Expected behavior

• Pressing ? opens the help dialog.
  Instead, nothing happens because the key event lookup fails.

Solution

• Further reviewing can be done in PR.
