A hot key control is a window that enables the user to enter a combination of keystrokes to be used as a hot key. A hot key is a key combination that the user can press to perform an action quickly. For example, a user can create a hot key that activates a given window and brings it to the top of the z-order. The hot key control displays the user's choices and ensures that the user selects a valid key combination. The following screen shot shows how a hot key control appears in a dialog box after the user presses the Alt key.

I have a macbook pro model 2,2 I found a way to map the 3rd symbol easily. In ubuntu 12.04, in system setting - keyboard configuration, choose options, there is a option called 3rd level (in spanish Tecla para seleccionar el 3er nivel), I chose the numeric intro that is the right key beside the right mac cmd key, and there you have it presing that key plus 2 I get the at symbol.

When the user enters a key combination to be used as a hot key, the names of the keys appear in the hot key control. A key combination can consist of a modifier key (such as CTRL, ALT, or SHIFT) and an accompanying key (such as a character key, an arrow key, a function key, and so on).
After the user has chosen a key combination, the application retrieves the key combination from the hot key control and uses it to set up a hot key in the system. The information retrieved from the hot key control includes a flag indicating the modifier key and the virtual key code of the accompanying key.
The application can use the information provided by a hot key control to set up a global hot key or a thread-specific hot key. A global hot key is associated with a particular window; it allows the user to activate the window from any part of the system. An application sets a global hot key by using the WM_SETHOTKEY message. Whenever the user presses a global hot key, the window specified in WM_SETHOTKEY receives a WM_SYSCOMMAND message that specifies the SC_HOTKEY value. This message activates the window that receives it. The hot key remains valid until the application that called WM_SETHOTKEY exits.
A thread-specific hot key generates a WM_HOTKEY message that is posted to the beginning of a particular thread so that it is removed by the next iteration of the message loop. An application sets a thread-specific hot key by using the RegisterHotKey function.
Hot Key Control Messages
After creating a hot key control, an application interacts with it by using three messages: HKM_SETRULES, HKM_SETHOTKEY, and HKM_GETHOTKEY.
An application can send the HKM_SETRULES message to specify a set of CTRL, ALT, and SHIFT key combinations that are considered invalid hot keys. If the application specifies an invalid key combination, it should also specify a default modifier combination to use when the user selects the invalid combination. When the user enters the invalid combination, the system performs a logical OR operation on the invalid combination and the default combination. The result is considered a valid combination; it is converted to a string and displayed in the control.
Nov 27, 2019 PHP Artisan Key:Generate (Aborted Error) #7625. Closed KCleveland313 opened this issue Nov 27, 2019 5 comments Closed. So for this issue what I did was use the command php artisan key:generate -show This will show u the key instead of adding it to the env file. Copy and paste the key from there and it worked. Php artisan key:generate needs an existing key to work. Fill the APPKEY with 32 characters and rerun the command to make it work. Edit: A newly created app via laravel new with a deleted APPKEY can run php artisan key:generate without issue for some reason. Edit a year later: The real problems lays in 2 added provider services.

What Key Combination Generates The Paragraph Symbol In Math
The HKM_SETHOTKEY message allows an application to set the hot key combination for a hot key control. This message is also typically used when the hot key control is created.
Applications use the HKM_GETHOTKEY message to retrieve the virtual key code and modifier flags of the hot key chosen by the user.
Hot Key Control Notifications
The hot key control does not send any notification codes via the WM_NOTIFY message. It will, however, send the EN_CHANGE notification via the WM_COMMAND message when the user changes the contents of the control.
Default Hot Key Message Processing
This section describes the window messages handled by the window procedure for the pre defined HOTKEY_CLASS window class used with hot key controls.
What Key Combination Generates The Paragraph Symbol Printable
Message | Processing performed |
WM_CHAR | Retrieves the virtual key code. |
WM_CREATE | Initializes the hot key control, clears any hot key rules, and uses the system font. |
WM_ERASEBKGND | Hides the caret, calls the DefWindowProc function, and shows the caret again. |
WM_GETDLGCODE | Returns a combination of the DLGC_WANTCHARS and DLGC_WANTARROWS values. |
WM_GETFONT | Retrieves the font. |
WM_KEYDOWN | Calls the DefWindowProc function if the key is ENTER, TAB, SPACE BAR, DEL, ESC, or BACKSPACE. If the key is SHIFT, CTRL, or ALT, it checks whether the combination is valid and, if it is, sets the hot key using the combination. All other keys are set as hot keys without their validity being checked first. |
WM_KEYUP | Retrieves the virtual key code. |
WM_KILLFOCUS | Destroys the caret. |
WM_LBUTTONDOWN | Sets the focus to the window. |
WM_NCCREATE | Sets the WS_EX_CLIENTEDGE window style. |
WM_PAINT | Paints the hot key control. |
WM_SETFOCUS | Creates and shows the caret. |
WM_SETFONT | Sets the font. |
WM_SYSCHAR | Retrieves the virtual key code. |
WM_SYSKEYDOWN | Calls the DefWindowProc function if the key is ENTER, TAB, SPACE BAR, DEL, ESC, or BACKSPACE. If the key is SHIFT, CTRL, or ALT, it checks whether the combination is valid and, if it is, sets the hot key using the combination. All other keys are set as hot keys without their validity being checked first. |
WM_SYSKEYUP | Retrieves the virtual key code. |
