copy of soft menu button in 50g

[samo50g]

I understand MENU, CST and I can create variables and use these two features. I also can use TMENU however I do not understand "where" exactly the created variable is located. i can see my variable at the bottom of display after i create it with TMENU, but after changing menus I cannot find it again. is this actually the difference between MENU and TMENU ? if yes, than all is clear.

P.S.: i have discovered that my created variable is in MENU .01 after creation with TMENU. So now I know where it is. is there anything which i should also be aware of? Maybe I can navigate to this variable with use of buttons?
