Activate / deactivate symbols
With this option it is possible to display in all available windows the symbols or mnemonics
associated to the various resources.
The names of the resources may be displayed in two ways: using their generic names (I, O, M, T,
C , R) by deactivating symbols or using their associated symbols by activating them.
When a resource has no mnemonic associated to it, it will always be displayed with its generic name.
This softkey will toggle between ACTIVATE SYMBOL and DEACTIVATE SYMBOL every time is
pressed in order to show which option is available.
