which is ctrl key in mobile phone from which you must bold your texts
Answers
Tab - move between items or move forward 5 characters (depending on the task).
Shift - when the Shift key is pressed at the same time as a letter key, an upper case version of that letter is produced. For other non-letter keys, this action produces the character that is above the main character on the key.
Alt Gr - used on international keyboards to access special characters on keys where there are more than two characters on the key. Press it down at the same time as the letter/character key to produce the special character shown on the bottom right side of the key.
Ctrl - holding down the Ctrl key while selecting items allows you to select several items at once. The Ctrl key is also used in many keyboard shortcuts.
Scroll Lock - in the past, when Scroll Lock was selected, pressing the arrow keys resulted in scrolling through a page of text rather than moving the cursor line by line. These days, the functionality has been replaced by the on-screen scroll bar, so the Scroll Lock key is almost never used and most recent applications don't recognize it.
Insert - pressing this key switches between two modes when you are typing. In the first mode, what you type appears before the cursor and pushes any text that comes after it to the right. In the second mode, any text that you type successively replaces any text that is to the right of the cursor.
Num Lock - When the Num Lock key is pressed, the numbers on the number pad of the keyboard are activated. When the Num Lock key is not pressed, it's the arrows and special keys on the number pad which are active. The number pad is a block of numbers that looks like an upside down telephone keypad. On desktop computer keyboards it is found on the right hand side of the keyboard. On laptops, the number pad is a special feature that is associated with regular keys on the keyboard. The numbers corresponding to the number pad can usually be seen on the bottom edge of other keys (usually ones on the right side of the keyboard).
Caps Lock - when you press the Caps Lock key, you activate a feature that lets you type upper case letters continuously without having to press the Shift key at the same time. To go back to typing lower case letters, press the Caps Lock key again. You should use Caps Lock instead of shift if you want to type more than one or two upper case letters in a row. Numbers and special keys are not affected by the Caps Lock key.
Print Screen - pressing the Print Screen key captures an image of your entire screen. For more on this feature see the section PrintScreen under Other useful things...
