There is a hidden option using which you can simulate bold and italic formatting styles for fonts that do not have these options. Click the button on the type tool option to bring up the character palette. Then select text and click the arrow in the upper right hand corner of the palette menu where faux bold and italics are present. However you will not be able to warp type when formatting has been applied. One can quickly flip through blend modes while trying out effects by using the keys “shift+ to change to next mode and shift- to go to the previous mode.” When a painting tool is active this shortcut will change the blend mode of the painting tool. However, if anything is highlighted then the shortcut will not work. You will have press esc and then use the shortcut keys again.

The photomerge feature can be used to seamlessly combine multiple images to create a panorama. This feature can be accessed from the Automate menu. You can even refine the composition using tools like rotate, zoom, pan, and set vanishing point. When re-sampling images one can use either Bicubic Smoother or Bicubic Sharper. You can use Bicubic smoother for up sampling and Bicubic sharper for down sampling. You can actually specify which interpolation method is to be used by going to general preferences and setting a default.
