ImageJ is easy to use, but sometimes you wish for some function that is actually implemented, yet you do not know how to trigger. This page lists a few of those tricks.

Show the memory consumption

Just click on the status bar, and you will see how much memory is used, and how much memory is available.

Execute external programs

The macro language allows executing programs, and capturing their output:

output = exec("dir /w");

Quickly see return values

You do not need to wrap calls into write() calls: if you just write something like

getDirectory("plugins");

the return value will appear in your Log window when called.

Find out in which menu (or .jar file) a certain command is

Hit Ctrl+L (or Cmd+L on Macs) to start the command launcher. Type (part of) the name of the entry, then click on Show full information.

If Edit>Options>Misc...>Require command key for shortcuts is unchecked, typing L is sufficient.

Put the main window to the foreground

Pressing the Return key on any image will bring the main window to the foreground.

Close all images (without being asked whether to save them)

Plugins>Utilities>Close All Without Saving
