The purpose of this page is to teach one how to type a literal sigma character using a keyboard.
- Remember, you can always copy and paste a sigma like you would with any other string. I still do not mind being called Sigma.
- Σ, Σ, or Σ can be used to display a sigma. These entities can also be used in the search box.
You can change the code page by changing the 'format' option (the dropdown box) under the 'Formats' tab at 'Control Panel' -> 'Region and Language'. There are alternatives to changing the code page, though.
Unicode input method platform
- It may be worth noting that this is only the configuration I use. Other input methods may support `u.
- This works on Windows 7.
- Go to 'Control Panel' -> 'Region and Language'.
- On the 'Keyboards and Languages' tab, press the 'Change Keyboards' button.
- A new window should have appeared. Press the 'Add' button.
- You should now see a list of languages with their countries. Under 'Chinese (Traditional, Taiwan)' check the box labeled 'Chinese (Traditional) - New Phonetic', and then OK.
- Select the field that says 'Chinese (Traditional, Taiwan)', and then press 'Properties'.
- Under the 'Advanced' tab, there should be a table mapping property names to your setting. Change the 'Leading key' field to the backtick (`) and then OK.
- Now, in the window that was opened in step 2, go to the 'Advanced Key Settings' tab. Change the key sequence for 'Chinese (Traditional) IME - Ime/NonIme Toggle' to Ctrl+Space.
- Save the changes. Logout and back in if nothing happened.
- Open your favourite text editor, hit Ctrl+Space, and type `u03a3, a space, and then hit ↵ Enter. A sigma should have appeared at the caret position.
- You can switch out of this input method by hitting Ctrl+Space again.
There are two common methods for direct input of Unicode characters. These methods will not work with SCIM installed.
- Hold Ctrl+⇧ Shift and type u followed by 03a3. Then release Ctrl + Shift.
- Enter Ctrl+⇧ Shift+u, then type 03a3, and press ↵ Enter or Space.
Installing SCIM will remove the capability described above. There is a package, scim-rawcode, that imitates that feature. You can set Ctrl+⇧ Shift+u to be the shortcut for switching to the rawcode input method. After switching to rawcode, you can type 03a3, and press ↵ Enter or Space.
On Classic Mac and OSX systems, option-w produces sigma.
