I have these mapped in my  gvimrc to let me hit command- arrow  to move the height and width of my current window around     resize current buffer by   - 5  nnoremap  lt D-left gt   vertical resize -5 lt cr gt  nnoremap  lt D-down gt   resize  5 lt cr gt  nnoremap  lt D-up gt   resize -5 lt cr gt  nnoremap  lt D-right gt   vertical resize  5 lt cr gt    For MacVim  you have to put them in your  gvimrc  and not your  vimrc  as they ll otherwise get overwritten by the system  gvimrc

In case you need HORIZONTAL SPLIT resize as well  The command is the same for all splits  just the parameter changes   -   instead of  lt   gt   Examples  Decrease horizontal size by 10 columns   10winc -   Increase horizontal size by 30 columns   30winc     or within normal mode   Horizontal splits  10 CTRL w  -  30 CTRL w     Vertical splits  10 CTRL w   lt   decrease   30 CTRL w     increase

Along the same lines  I use the following in my  vimrc to let me move through the splits  automatically expanding the one I m moving to to its full size and shrinking all the rest to their minimum height or width     Switch between window splits using big J or K and expand the split to its    full size        Move vertically in the window through the horizontal splits     map  lt C-J gt   lt C-w gt j lt C-w gt    map  lt C-K gt   lt C-w gt k lt C-w gt       Move horizontally in the window through the vertical splits     map  lt C-H gt   lt C-w gt h lt C-w gt     map  lt C-L gt   lt C-w gt l lt C-w gt

Another tip from my side   In order to set the window s width to let s say exactly 80 columns  use  80 CTRL W     In order to set it to maximum width  just omit the preceding number   CTRL W
