| - | | array separator (,) | separates elements of an array | | + | | Array Separator (`,`)\\ FIXME -- this is NOT an //operator// IMO. | Allows a text Variable, which has comma separated values, to work somewhat like an Array.\\ Assume `MyKMVariable` contains "value1,value2,value3".\\ Then `MyKMVariable[2]` returns "value2". | |
| - | | ternary operator (?) | a=b ? 3 : 4 | | + | | Ternary Operator (`?`) | a=b ? 3 : 4 | |
| - | | bitwise or (%%|%%), bitwise and (%%&%%) and bitwise xor | operators | | + | | Bitwise OR (`|`), Bitwise AND (`&`) and Bitwise XOR | operators | |
| - | | comparison operators (<, ≤, =, >, ≥, ≠) | compare for (in)equality and return 0 or 1 | | + | | Comparison Operators (`<, ≤, =, >, ≥, ≠`) | compare for (in)equality and return 0 or 1 | |
| - | | shift operators (≪, ≫) | shift a number left or right | | + | | Shift Operators (`≪, ≫`) | shift a number left or right | |
| - | | addition operators (+, -) | add or subtract | | + | | Arithmetic Operators\\ • Add (`+`)\\ • Subtract (`-`)\\ • Multiply (`*`)\\ • Divide (`/`) | A mathematical function that takes two operands and performs a calculation on them. | |
| - | | multiplication operators (*, /, MOD) | multiply, divide or [Modulo](https://en.wikipedia.org/wiki/Modulo_operation) | | + | | [Modulo](https://en.wikipedia.org/wiki/Modulo_operation) (`i MOD n`) | The remainder of the division of i by n.\\ Both values (`i, n`) must be integer in Keyboard Maestro. | |
| - | | power operator (%%^%%) | exponentiation | | + | | Power Operator (`^`) | exponentiation | |
| - | | unary prefix operators (√ (Option-V), -, brackets) | square root, negation, sub-expressions | | + | | Unary Prefix Operators (`√`, `-`, `( )` ) | square root, negation, sub-expressions | |
| - | | functions | a large variety of functions | | + | | functions\\ FIXME -- While technically Functions are operators, it confusing to most users to list here since everywhere else in KM they are separated. | a large variety of functions | |
| - | | numbers and variables or array accesses (5,$5A,0x50,8#007,Variable,Variable[5]) | identifiers and values | | + | | Numbers and Variables or Array Accesses (5,$5A,0x50,8#007,Variable,Variable[5])\\ FIXME -- this is clear as mud. | identifiers and values | |
| - | | unary postfix operators (!,%,° (Option-Shift-8)) | factorial, percent, degrees | | + | | Unary Postfix Operators (`!,%,°`)) | factorial, percent, degrees | |
