You can add exceptions if you don't want certain combinations to be remapped (for example, cmd-tab) by adding a new global shortcut with the action 'Do Not Remap' and the keystroke of the (unremapped) key you wish to keep unaffected by modifier remapping. Set Left option key to Left command key and Left command key to Left option key (and do the same for Right command and Right option if you please). One common need is to exchange cmd and option. You have separate control over left and right command and option keys. This window is called the 'hotkey window' and is most commonly used for occasional administrative tasks.

ITerm2 offers a special terminal window that is always available with a single keystroke. Pressing the shortcut again restores the hidden panes. You can 'maximize' the current pane-hiding all others in that tab-with cmd-shift-enter. You can navigate among split panes with cmd-opt-arrow or cmd. The shortcuts cmd-d and cmd-shift-d divide an existing session vertically or horizontally, respectively. ITerm2 allows you to divide a tab into many rectangular 'panes', each of which is a different terminal session. In Prefs > Profiles > Keys you can assign keys to move the beginning or end of the selection by a single character, word, or line. You can bind keystrokes to create and adjust selections.At most one line of text can be selected this way. To move the beginning of the selection to the left, press shift-tab. Then press tab and the end of the selection will advance by a word. Enter the beginning of the text you wish to copy and the find feature will select it in your window. To select text without using the mouse, press cmd-f to open the find field. You can use the find feature's 'mouseless copy' feature.There are several ways to select text to copy to the clipboard: This chapter describes features of iTerm2 that go beyond basic usage and are not generally found in other terminal emulators.
