In tmux can I resize a pane to an absolute value

Question

Is it possible to tell tmux to \"resize a pane to 5 lines high\"?

I know I can do resize-pane -U 3 to move the dividing line, but sometimes when logging in

Answer 1

In tmux 1.8, the size of the panes may be adjusted interactively. Under the default key bindings this may be done by the prefix key (C-b) followed by the meta key combined with arrow keys (M-arrow), where arrow is one of the up/down/left/right arrow keys.

E.g. Ctrl-b followed by Alt-Up will adjust the size upwards.

Note that the Alt key may be held down while the up/down/left/right keys are pressed multiple times to make multiple adjustments.

E.g. Ctrl-b followed by Alt-Up-Up-Left will adjust the size upwards by two movements and left by one movement.
