Q

Hetero atom

C, N, H, ...

carbon, nitrogen or hydrogen atom. For the other elements, type the mark of the element, e.g.: Cl for Chlorine. (Also works in lower case: n, cl etc.)

Au,Ag,Pt,...

Atom List can be defined by typing chemical symbols separated by commas. (Also works in lower case: au,ag,pt,...)

!Au,Ag,Pt,...

Not List can be defined by starting the atom list with an exclamation mark. (Also works in lower case: !au,ag,pt,...)

R1, R2, ..., R32767

R-group label with specified number. To define a set of fragments as R-group, select the fragments before the shortcut. To create an attachment point in the R-group, select an atom in the R-group and type the name of the R-group (e.g.: R5) (Also works in lower case.)
To define a set of fragments as R-group 5, select the fragments then type R5. After then, you can choose an attachment point on R-group 4, just type R5 and click on the atom.

M1, M2, ...

Atom maps for reactions. (Also in lower case.)

M0

Unmap

M= or M+

Unique atom map labels. Assigns unique atom map numbers to individual atoms picked by the mouse or to selected atoms in selection mode.

11, 22, ..., 77

Select a template. Select first, second, ..., or 7th element from the actual template list from the toolbar (if the referred index is not out of range).

abs, or1, or2, and1, and2

Stereochemical groups: abs (ABSOLUTE),\ or1,or2,...,or10,... (OR n), and1,and2,...,and10,...,&1,&2,..., &10,... (AND n)

AcAc, Acm, Ade, ...

The abbreviated group denoted by the abbreviation. You can ungroup the abbreviated group if you press the SHIFT button when you place it to the canvas. (Also in lower case.) To complete a longer name, press ENTER or END after typing the first few characters.

.a,.A,.u,.H0,H1

Special atom properties: .a (aromatic), .A (aliphatic), .u (unsaturated), .H0, .H1, ... (number of hydrogens), .h0, .h1, ... (implicit hydrogens), .X0, .X1, ... (connectivity), .D0, .D1, ... (degree), .R0, .R1, ... (rings), .r3, .r4, ... (smallest ring size), .s*, .s0, .s1, ... (substitution count), .v0, .v1, ... (valence), .rb*, .rb0, .rb1, ... (ring bond count).
