Also in optics, it denotes wavelength of light. In politics, the lambda is the symbol of Identitarianism, a white nationalist movement that originated in France before spreading out to the rest of Europe and later on to North America, Australia and New Zealand. The Identitarian lambda represents the Battle of Thermopylae.
It is equal to the ordinary wavelength reduced by a factor of 2π (ƛ = λ/2π), with SI units of meter per radian. It is the inverse of angular wavenumber (k = 2π/λ). It is usually encountered in quantum mechanics, where it is used in combination with the reduced Planck constant (symbol ħ, h-bar) and the angular frequency (symbol ω = 2πf).
The barred lambda ( ƛ) (U+A7DC LATIN CAPITAL LETTER LAMBDA WITH STROKE, U+019B ƛ LATIN SMALL LETTER LAMBDA WITH STROKE), is a modified letter of the Greek alphabet, commonly encountered in North American linguistics.

Many keyboard shortcuts will work on either a Windows-based PC or a Mac. Often, the main difference is that you press Ctrl on a PC but Command (look for the ⌘ symbol) on a Mac.
In computing, a keyboard shortcut is a sequence or combination of keystrokes on a computer keyboard which invokes commands in software.. Most keyboard shortcuts require the user to press a single key or a sequence of keys one after the other.
The most common symbols for a wave function are the Greek letters ψ and Ψ (lower-case and capital psi, respectively). Wave functions are complex-valued. For example, a wave function might assign a complex number to each point in a region of space.
