Local variables, instance variables, and class variables are also written in lowerCamelCase. Variable names should not start with underscore (_) or dollar sign ($) characters, even though both are allowed. This is in contrast to other coding conventions that state that underscores should be used to prefix all instance variables.
A variable's identifier must start with a letter, underscore (_), or dollar sign ($), while subsequent characters can also be digits (0-9). JavaScript is case sensitive, so the uppercase characters "A" through "Z" are different from the lowercase characters "a" through "z".
Most keyboard shortcuts require the user to press a single key or a sequence of keys one after the other. Other keyboard shortcuts require pressing and holding several keys simultaneously (indicated in the tables below by the + sign). Keyboard shortcuts may depend on the keyboard layout.
To use the shortcut, turn on NumLock / Fn, and make sure the cursor is flashing where you want the symbol to go. Press and hold the alt key, and then press numbers. You don’t need to press the ...
The last global variable subtree may be referenced indirectly by a caret and the last subscript; this is referred to as a "naked reference". System-wide routines and global variables (stored in certain shared database(s)) are prefixed with ^%; these are referred to as "percent routines" and "percent globals".
The currency sign was once a part of the Mac OS Roman character set, but Apple changed the symbol at that code point to the euro sign in Mac OS 8.5.In pre-Unicode Windows character sets (Windows-1252), the generic currency sign was retained at 0xA4 and the euro sign was introduced as a new code point, at 0x80 in the little used (by Microsoft) control-code space 0x80 to 0x9F.
In computing, a keyboard shortcut (also hotkey/hot key or key binding) [1] is a software-based assignment of an action to one or more keys on a computer keyboard.
A variable can eventually be associated with or identified by a memory address. The variable name is the usual way to reference the stored value, in addition to referring to the variable itself, depending on the context. This separation of name and content allows the name to be used independently of the exact information it represents.
