ABAP Editor settings?

Hi,

Our SAP is EHP6 and BASIS is 731 w/ 4.

Pls. let me know how can I get the below settings / features?

1) Say, I declared as below

DATA lv_matnr TYPE matnr.

DATA ls_mara TYPE mara.

So, when I use these (lv_matnr, lv_mara) in my ABAP programming then the ABAP editor pops me (tool tip kind) helps me to populate / suggest them, the moment I typed lv_ .....

Pl. let me know where is the setting I need to do?

2) See below comments in red box, as soon as put this class/method automatically am getting the variable's labels, how can I get for me?

Thank you
