How to type (insert, enter) symbol alpha α, micro μ, pi π, degree…in Word, Excel

There are 2 tips for writing super-fast special characters in MS Word with just the keyboard, no need using of mouse, no need to insert and search symbols, saving time when editing text:

TIP 1:
Press shortcut key Ctr+Shift+Q then type a to enter alpha symbol (α)
Press shortcut key Ctr+Shift+Q then type b to enter beta symbol (β)
Press shortcut key Ctr+Shift+Q then type d to enter delta symbol (δ)
Press shortcut key Ctr+Shift+Q then type D to enter delta symbol (Δ)
Press shortcut key Ctr+Shift+Q then type m to enter micro symbol (μ)
Press shortcut key Ctr+Shift+Q then type p to enter PI symbol (π)
Press shortcut key Ctr+Shift+Q then type r to enter ro symbol (ρ)
Press shortcut key Ctr+Shift+Qthen type e to enter epsilon symbol (ε)
Press shortcut key Ctr+Shift+Q then type f to enter phi symbol (φ)
Press shortcut key Ctr+Shift+Q then type g to enter gamma symbol (γ)
Press shortcut key Ctr+Shift+Q then type l to enter lambda symbol (λ)
Press shortcut key Ctr+Shift+Q then type w to enter omega symbol (ω)
Press shortcut key Ctr+Shift+Q then type W to enter Ohm symbol (Ω)
Press shortcut key Ctr+Alt+C to enter Copyrights symbol © (Circle C)
Press shortcut key Ctr+Alt+R to enter Register symbol ® (Circle R)
Press shortcut key Ctr+Alt+M to enter Trade Mark symbol ™ (Trade Mark)

TIP 2:
Type 03b1 then press shortcut key Alt+X we will get α (alpha)

Type 03b4 then press shortcut key Alt+X we will get δ (small delta)
Type 0394 then press shortcut key Alt+X we will get Δ (large delta)
Type 03bc then press shortcut key Alt+X we will get μ (micro)
Type 03c0 then press shortcut key Alt+X we will get π (numberical pi)
Type 03c1 then press shortcut key Alt+X we will get ρ (ro, resistance rate)
Type 03b5 then press shortcut key Alt+X we will get ε (epsilon)
Type 03c6 then press shortcut key Alt+X we will get φ (phi)
Type 03b3 then press shortcut key Alt+X we will get γ (gama)
Type 03bb then press shortcut key Alt+X we will get λ (lamda)
Type 03c9 then press shortcut key Alt+X we will get ω (small omega)
Type 2126 then press shortcut key Alt+X we will get Ω (large omega, Ohm unit)
Type 00a9 then press shortcut key Alt+X we will get © (C tròn)
Type 00ae then press shortcut key Alt+X we will get ® (R tròn)
Type 2122 then press shortcut key Alt+X we will get ™ (Trade Mark)
Type 02da then press shortcut key Alt+X we will get ˚ (degree C)
