My radial and mirror attachment buttons don't work with my keyboard anymore

[SpaceFace545]

I used to be able to press x and switch between radial and mirror symmetry modes but after I uninstalled editor extensions this stopped working.

[OHara]

So put them back by running KSP and then  at Main-Menu choosing Settings : Input : Game : Editor

Defaults are 'R' to toggle between Radial and Mirror, 'X' to Cycle between the number of items (1, 2, and in radial symmetry 3 4 6 8) to be placed at once

Yeah, it happens sometimes that those two key bindings are lost. Either use @OHara's method, or, if you're not using EEX, you can simply edit your settings.cfg, the respective lines are:

Spoiler

Editor_toggleSymMode
{
    primary = X
    secondary = None
    group = 0
    modeMask = -1
    modeMaskSec = -1
}
Editor_toggleAngleSnap
{
    primary = C
    secondary = None
    group = 0
    modeMask = -1
    modeMaskSec = -1
}

Just put X and C back there and you're good.

Tip: make a backup of your settings.cfg
