feat: Add Missing Keyboard Shortcuts to Help List UI

[silentoplayz]

Is your feature request related to a problem? Please describe.

Yes, the problem is that the Open WebUI keyboard shortcuts list is missing some commonly used and useful keyboard shortcuts, such as Shift+Enter for new line, Ctrl/⌘+Shift+R for refreshing the current tab, and F11 or Ctrl/⌘+Shift+F for entering and exiting full-screen mode.

Describe the solution you'd like

I would like the following keyboard shortcuts to be added to the keyboard shortcuts help list UI:

1. Shift+Enter for a new line
2. Ctrl/⌘+Shift+R for refreshing the current tab
3. F11 or Ctrl/⌘+Shift+F for entering and exiting full-screen mode
   These shortcuts are already built into most modern web browsers, and including them in the help list will enhance the user experience.

Here are the detailed descriptions of the suggested keyboard shortcuts:

1. Shift+Enter for a new line: This shortcut allows users to create a new line while typing in a text area or input field. Currently, this shortcut is not listed in the Open WebUI keyboard shortcuts help list.
2. Ctrl/⌘+Shift+R for refreshing the current tab: This shortcut reloads the current tab in the browser. This shortcut is not listed in the Open WebUI keyboard shortcuts help list.
3. F11 or Ctrl/⌘+Shift+F for entering and exiting Fullscreen mode: These shortcuts allow users to enter and exit Fullscreen mode in Open WebUI. Additionally, Ctrl/⌘+Shift+F is not mentioned at all.

Additional context

• Ensure that keyboard shortcuts are consistent across the entire application. For example, if a particular action has a specific shortcut in one part of the application, it should have the same shortcut in other parts of the application as well.
• Global vs. local shortcuts: Clearly differentiate between global shortcuts (applicable across the entire web app) and local shortcuts (specific to certain pages or components).
• Group shortcuts by functionality: Organize shortcuts into categories based on their functionality, such as navigation, chat management, and settings. This will help users find and learn the shortcuts relevant to their needs.
• Show shortcut hints: Display a small, unobtrusive hint in the UI when a user can use a keyboard shortcut. For example, when a user hovers their mouse button above the New Chat button, display a hint saying Or press "Ctrl+N" to create a new chat.
• Prefer two-key combinations over three-key combinations when possible.
• Avoid using modifier keys (Ctrl, Shift, Alt, etc.) in isolation, as they are often used in other applications for different purposes.
• Allow users to edit/customize and save keyboard shortcuts according to their preferences.
• Add a Clear or Remove button next to each shortcut in the keyboard shortcuts menu. When users click on this button, the associated shortcut field would be cleared, effectively removing the binding.
• Implement a hotkey conflict resolution system: If a user tries to set a keyboard shortcut that conflicts with an existing one, provide a clear warning and an option to either change the conflicting shortcut or keep the new one.
• Provide a way to import and export custom shortcut sets for easy sharing and backup.
