Ribbon-ul este este un set de toolbars care sunt afisate in partea de sus a ferestrei si sunt concepute pentru a ne ajuta sa gasim rapid comenzile de care avem nevoie pentru a finaliza un anumit task.
Daca avem nevoie de mai mult spatiu pe ecran, il putem ascunde temporar. Putem face asta in 3 moduri.
[mai mult...]Putem modifica foarte usor size-ul font-ului ducandu-ne in Word pe tab-ul Home -> Font si aici selectand ce dimensiune dorim.Dar mai exista doua shortcut-uri care fac exact acelasi lucru.

Sample session from version 8.4:
Putem deschide Windows Explorer in mai multe moduri: apasand combinatia de taste Windows + E, din Run sau din Command Prompt. Pentru a-l deschide din CMD trebuie sa rulam comanda explorer.
[mai mult...]Implicit comenzile Insert Rows Above&Below nu exista in Quick Access Toolbar. Pentru a le accesa fara a avea acest shortcut-uri trebuie sa facem click dreapta intr-un rand din tabel si sa selectam comanda Insert – Insert rows.
Daca lucrati foarte mult cu tabele in Word adaugarea unui shortcut pentru a insera un nou rand va poate ajuta sa castigati timp. Vom exemplifica in Word 2010.
[mai mult...]Uneori, cand va conectati un stick USB la computer, portul USB continua sa se deconecteze și sa se reconecteze la fiecare cateva secunde sau uneori minute. Fapt care duce la situatia in care daca avem nevoie sa transferam fisiere pe stick-ul de memorie usb sau invers, vom intampina mari probleme.
