You can also add an alternative keyboard layout, then you can switch between both layouts as necessary. http://www.aufgehts.com/sup_Germankeyboard.html#AddWinVista The disadvantage is that you'll have to remember where the new keys are.

use ALT Codes: Alt Code Symbol Description Alt 224 α Alpha Alt 225 ß Beta Alt 226 Γ Gamma Alt 235 δ Delta Alt 238 ε Epsilon Alt 233 Θ Theta Alt 227 π Pi Alt 230 µ Mu Alt 228 Σ Uppercase Sigma Alt 229 σ Lowercase sigma Alt 231 τ Tau Alt 232 Φ Uppercase Phi Alt 237 φ Lowercase Phi Alt 234 Ω Omega
