mine can't find MC - is it an app on the download facility?
Or you could use also vi, it comes preinstalled with n900. The controls are little bit odd though if you're never used it before.
Basically there's 2 modes in vi, edit & command mode, it starts with command mode, to enter insert mode where you can edit the text press i once, find the part you want to edit and change the values. To return to command mode hit esc. To quit write :x to quit & save or :q to quit without saving, or if it complains about changes not saved write :quit!
With the new release there's a file to edit for snap to grid.
File /usr/share/hildon-desktop/transitions.ini has a line named snap_grid_size = 4 around line number 182. Edit the value bigger to have more notiacable effect of snapping. I have it on 8 currently and it works pretty well. Though still no snapping to same line as nearest objects, only makes it easier to put icons on same level.
